Overview
This hands-on lab allows you to follow and experiment with the critical
steps of developing a program including the program description,
analysis, test plan, design, and implementation with C code.
Program Description
This program will sum two integer numbers to yield a third integer
number. Once the calculations are made the results of all the numbers
will be printed to the output screen.
Analysis
We will use sequential programming statements.
We will define 3 integer numbers: a, b, c.
c will store the sum of a and b.
Test Plan
To understand this program the following input numbers could be used
for testing:
a = 10
b = 20
c = a + b = 10 + 20 = 30
In table format the following results are expected:

Description
This program will calculate the area of a right triangle. The program will
ask the user to enter the base and height and then use these values to
calculate and then print the area of the triangle. The design step will
include pseudocode.
Analysis
I will use sequential programming statements. I will define two float
numbers for the base and height: base, height. Float numbers were

selected as opposed to integers to make sure triangles of all dimensions
are possible and not just whole numbers.
Float number will store the area: area
The area will be calculated by this formula:
Area = ½ * (base * height)
For example if the base was 4.2 and the height was 5.3 the area would be
calculated as:
Area = ½ * (4.2 * 5.3) = ½ * (22.26) = 11.13
Test Plan
To verify this program is working properly the following base and
height values could be used for testing:

CMIS 102 Hands-On Lab
Week 4
Overview
steps of developing a program
including the program description, analysis, test plan, design (using
pseudocode), and implementation
with C code. The example provided uses sequential and selection
statements.
Program Description
This program will calculate the sum of 5 integers. The program will ask
the user to 5 integers. If the sum

of the numbers is greater than 100, a message is printed stating the sum
is over 100. The design step will
include both pseudocode.
Analysis
I will use sequential, and selection programming statements.
I will define six integer numbers: value1, value2, value3, value4, value5
and sum. The value1, value2,
value3, value4 and value5 variables will store the integers input by the
user. The sum will store the sum
of the 5 values.
The sum will be calculated by this formula:
sum = value1 + value2 + value3 + value4 + value5
For example, if the first values entered were value 1=1, value 2=1, value
3=2,value 4=2 and value 5=3
respectively:
sum = 1 + 1 + 2 + 2 + 3 = 9
The additional selection statement will be of this form:
If sum > 100 then
print "Sum is over 100"
End If Test Plan
To verify this program is working properly the input values could be
used for testing:

Overview
analysis, test plan, design (using pseudocode), and implementation with

C code. The example provided uses sequential, selection and repetition
statements.
Program Description
This program will calculate the average of 10 positive integers. The
program will ask the user to 10 integers. If any of the values entered is
negative, a message will be displayed asking the user to enter a value
greater than 0. The program will use a loop to input the data.
Analysis
I will use sequential, selection and repetition programming statements. I
will define two integer numbers: count, value and sum. count will store
how many times values are entered. value will store the input. Sum will
store the sum of all 10 integers. I will define one double number: avg.
avg will store the average of the ten positive integers input.
1. Change the code to average 20 integers as opposed to 10. Support
your experimentation with screen captures of executing the new code.
and expected output for the code you created after step 1.
3. What happens if you entered a value other than an integer? (For
example a float or even a string). Support your experimentation with
screen captures of executing the code.
4. Modify the code to allow the user to enter an unspecified number of
positive integers and calculate the average. In other words, the user
could enter number of positive integers. (Hint: You can prompt the user
for how many they want to enter. Or; you could use a sentinel value to

trigger when the user has completed entering values). You may need to
conduct some research on your own to solve this problem. Prepare a new
test table with at least 3 distinct test cases listing input and expected
output for the code you created. Support your experimentation with

**********************************************************
Overview
analysis, test plan, design and implementation with C code. The example
provided uses sequential, repetition statements and nested repetition
statements.
Program Description

This program will calculate the average of 3 exams for 5 students. The
program will ask the user to enter 5 student names. For each of the
students, the program will ask for 3 exam scores. The average exam
score for each student will be calculated and printed.
Analysis
I will use sequential and repetition programming statements.
I will define one String to store the student name: StudentName.
I will define three Float numbers: Examvalue, Sum, Avg to store exam
values the sum of the exams and the average of the exams.
Sum = Sum + Examvalue
For example, if the first value entered was 80.0 and second was 90.0 and
the third exam was 100.0: sum = sum + Examvalue = 0.0 + 80.0
sum = 80.0 + 90.0 = 170.0
sum = 170.0 + 100.0 = 270.0
Avg is then calculated as:
Avg = sum/3.0
For example 270.0/3.0 = 90.0
A nested repetition loop can be used to loop through each of the 5
students and each of the 3 exams:
For (students=0; students <5; students++) For
(exams=0;exams<3;exams++) End For End For Sum values will need to
be reset for each student to ensure only one student data is used for
calculations each time.Test Plan

To verify this program is working properly the input values could be
used for testing:
1. Modify the code to be able to input an undetermined number of
students. You will still only have 3 exams for each student. Support your
experimentation with screen captures of executing the new code.
3. What is the line of code doing?
charStudentName[100];
(Hint: We haven’t covered arrays, but a String can be thought of as an
array of characters) ?
4. What would happen if you moved the Set Sum = 0.0 from inside the
for loop to right after the declaration. For example:
// Declare variables
Declare StudentName as String Declare ExamValue, Sum, Avg as Float
// Initialize Sum Set Sum = 0.0;
Support your experimentation with screen captures of executing the new
code.

Overview
steps of developing a program
including the program description, analysis, test plan, design, and
implementation with C code. The
example provided uses sequential, repetition, selection statements and
two user-defined function.
Program Description
This program will provide options for a user to calculate the square or
cube of a positive Integer input by a user. The program will prompt the
user to enter an Integer and then prompt the user if they want to
calculate the square of the cube of the number. Based on the inputs of
the user, the program will output
the square of the cube of the positive integer. The program will then
print the Integer and square or cube of the integer based on the user’s
original choice. The program will continue to prompt the user for

Integers and their calculation choice until the user enters a negative
integer. The square and cube calculations should be calculated using a
function.
Analysis
I will use sequential, selection, and repetition programming statements
and functions for the cube and
square calculations. I will define three Integer numbers: IntValue,
MenuSelect, Results to store the Integer value input by the user, the
Menu selection (1 for Square, 2 for Cube) of the user, and the results of
the Square or Cube functions.
The Square function will take one Integer as input and return one Integer
as the output. The calculation within the Square function is: Results =
IntValue * IntValue
For example: if 10 was entered as the IntValue. Results = 10*10 = 100
The Cube function will take one Integer as input and return one Integer
as the output. The calculation
within the Cube function is: Results = IntValue * IntValue*IntValue
For example: if 10 was entered as the IntValue. Results = 10*10*10 =
1000
A repetition loop can be used to loop through iterations until a negative
is entered:
1. Using the Square and Cube functions as models, Create an application
that includes a function named “Shrink” that would take an Integer and
return the Integer divided by 2? (Hint: your returned value should

probably be a double type.) Support your experimentation with screen
captures of executing the new code.
3. What would happen if you removed the following code from our
design? If intValue> 0 Support your argument with screen captures of
executing the new code.
4. Modify the original code and add an additional function of your
choice. The function should be unique and something you created for
this assignment. Support your experimentation with screen captures of
executing the new code. Prepare a test table with at least 3 distinct test
cases listing input and expected output for your unique function.

Overview:
Analysis, Design(program design, pseudocode), Test Plan, and
implementation with C code. The example provided uses sequential,
repetition, selection statements, functions, strings, and arrays.
Program Description:
This program will input and store meteorological data into an array. The
program will prompt the user to enter the average monthly rainfall for a
specific region and then use a loop to cycle through the array and print
out each value. The program should store up 5 years of meteorological
data.
Analysis:
I will use sequential, selection, and repetition programming statements
and an array to store data.
I will define a 2-D array of Float number: Raindata[][] to store the Float
values input by the user. To store up to 5 years of monthly data, the
array size should be at least 5*12 = 60 elements.
A float number (rain) will also be needed to input the individual rain
data.
An integer variable (Count) is needed to keep count of how many rain
data elements were entered. This will keep track to make sure we don’t
go over 60 and we print only valid rain elements. In a 2D array this will
be RainData[5][12]. We can use #defines to set the number of years and
months to eliminate hard coding values.

A float number (rain) will also be needed to input the individual rain
data. A nested for loop can be used to iterate through the array to enter
Raindata. A nested for loop can also be used to print the data in the
array. A array of strings can be used to store year and month names.
This will allow a tabular display with labels for the printout. Functions
will be used to separate functionality into smaller work units. Functions
for displaying the data and inputting the data will be used.
A selection statement will be used to determine if data should be
entered.
Learning Exercises for you to try:
1. Modify the program to add a function to sum the rainfall for each year
(Hint: you need to sum for each year. You can do this using a looping
structure) Support your experimentation with screen captures of
executing the new code
2. Enhance the program to allow the user to enter another meteorological
element such as windspeed (e.g. 2.4 mph). Note, the user should be able
to enter both rainfall and windspeed in your new implementation.
Support your experimentation with screen captures of executing the new
code.
and expected output for the code you created after step 2
4. What happens if you change the NUMMONTHS and NUMYEARS
de finitions to other values? Be sure to useboth lower and higher values.
Describe and implement fixes for any issues if errors results. Support
your experimentation with screen captures of executing the new code.
