Basic Programming in C++
Session 1

C is developed by Dennis Ritchie
C is a structured programming language
C supports functions that enables easy
maintainability of code, by breaking large file
into smaller modules
Comments in C provides easy readability
C is a powerful language

Creating Programs
Source File
(High-Level Languages)
Object File
(Machine Languages)
Executable
gcc –o hello hello.cnedit hello.c

Program Structure C + +

Structure of C + + Coding

Input
 scanf
 getchar
 gets
Basic Commands C++
Output
 printf
 putchar
 puts

Input
 scanf(“%d”,&a);
 Gets an integer value from the user and stores it
under the name “a”
Output
 printf(“%d”,a)
 Prints the value present in variable a on the
screen
Basic Commands C++

Single line comment
 // (double slash)
 Termination of comment is by pressing enter key
Multi line comment
/*….
…….*/
This can span over to multiple lines
Comments in C++

1./* Hello, world program */
2.#include <stdio.h>
3.
4.int main()
5.{
6. printf("hello, ");
7. printf("worldn");
8. return 0;
9.}
Simple Program

Type a program
Save it
Compile the program – This will generate an
exe file (executable)
Run the program (Actually the exe created out
of compilation will run and not the .c file)
In different compiler we have different option
for compiling and running. We give only the
concepts.
Running a C Program

Write a program to display your identity with a
form below :
------------------------------------------------------
AUTO BIOGRAFI
------------------------------------------------------
Name : <nama>
Address : <alamat>
Place of Birth : <tmp_lahir>
Date of Birth : <tgl_lahir>
Hobby : <hobby>
------------------------------------------------------
