8. INTRODUCTION TO C PROGRAMMING
C is a general-purpose, procedural programming language that was developed in the
early 1970s by
Dennis Ritchie at Bell Labs. It is known for its efficiency and control, which makes it a
popular choice for
system programming, embedded systems, and real-time applications.
Key Features of C
1.Structured Programming: C promotes modularity and code organization through
functions and blocks.
2.Low-Level Access: C allows direct manipulation of memory and hardware, enabling fine-
grained
control over system resources.
3.Efficiency: C code is compiled into machine code, resulting in highly efficient and fast-
running
programs.
4.Portability: C programs can be compiled and run on various platforms with minimal
modifications.
5.Rich Standard Library: C offers a comprehensive standard library with functions for
9. Basic Input and Output Functions :-
Input and output operations are fundamental to any program. They enable the
program to interact
with the user, read data from files, and display results. In C, the standard input/output
library
provides the following essential functions:
➢ Printf() function:
• Used to print formatted output to the console.
• Syntax: printf("format string", argument1, argument2, ...);
• Example:
printf("Hello, world!n");
printf("The value of x is %dn", x);
➢ Scanf() function:
• Used to read formatted input from the console.
• Syntax: scanf("format string", &variable1, &variable2, ...);
• Example:
int age;
printf("Enter your age: ");
scanf("%d", &age);
10. Importance of Input and Output
Functions
• User Interaction:
Input and output functions allow programs to communicate with users,
prompting them for input and displaying results.
• Data Processing:
Programs can read data from files or other sources, process it, and write
the results to files or the console.
• Debugging:
Input and output functions can be used to print intermediate values and
trace the execution of a program to identify and fix errors.
11. PROGRAMS:
#include<stdio.h>
int main()
{
int n, reversed = O ,remainder , original;
printf(“Enter an integer”);
scanf(“%d”,&n);
original =n;
where(n! = 0)
{
remainder = n % 10;
reversed = reversed*10+ remainder;
n/=10;
}
if( original == reversed)
12. {
printf(“%d is a palindrome”, original);
}
else
{
printf(“%d is n0t a palindrome”.original);
}
return 0;
}
13. #include <stdio.h>
int main()
{
int num, originalNum, remainder, result = 0;
printf("Enter a three-digit integer: ");
scanf("%d", &num);
originalNum = num;
while (originalNum ! =0)
{
remainder = originalNum % 10;
result += remainder * remainder * remainder;
originalNum /= 10;
}
if (result == num)
{
printf("%d is an Armstrong number.", num);
15. Real-Time Applications of Simple
C Programs with printf() and scanf()
While C is a powerful language often used for complex systems, even simple C programs utilizing
printf() and scanf() can have practical real-world applications. Here are a few examples:
➢ Data Entry and Validation:
1. Create a program to input personal details like name, age, and address.
2. Implement checks to ensure input is valid (e.g., age is a positive integer, email has the
correct
format).
3. Simulate a basic form where users input information, which can be processed and
stored.
➢ Basic Calculations:
1. Develop a simple calculator to perform arithmetic operations like addition,
subtraction, multiplication, and division.
2. Create a program to convert units (e.g., Celsius to Fahrenheit, kilometres to miles).
3. Calculate simple interest, compound interest, or loan repayments.
16. Key Considerations for Real-Time Applications:
➢ Efficiency :
Optimize code for speed and resource usage, especially in
embedded systems.
➢ Error Handling :
Implement robust error handling to prevent unexpected
behaviour.
➢ User Interface :
Design user-friendly interfaces, even for simple programs.
➢ Security :
Consider security implications, especially when dealing with
sensitive data.
➢ Testing :
Thoroughly test your code to ensure it works as expected.
By mastering the fundamentals of printf() and scanf(), you can
build the foundation for more complex C
