After reading this C while loop topic, you will understand the while loop flowchart, theory, and examples.
C while loop executes statements as long as expression evaluates to true condition and when the expression evaluates false condition the while loop gets terminate.
General Form (Syntax):
The syntax of while loop is given below,
while(expression)
{
statement(s);
}
As the while loop starts, expression gets evaluated and as the evaluated condition is true then the statement(s) inside the braces (i.e. {}) will execute.

The flow chart of while loop is given below,
Example:
Program (1): To print a message “how are you” five times using while loop.
#include<stdio.h>
#include<conio.h>
void main(void)
{
int i=1;
while(i<=5)
{
printf("How are you \n");
++i;
}
getch();
}
Output (1)
