C While Loop is a loop statement which can be used in various forms to execute a block of code continuously as long as the condition of the loop is true, and stops only when the condition fails. These are:
While Loop :
While loop is used to execute a group of action as long as the specified condition is true.
Syntax:
while (condition)
{
code to be executed if the condition is true;
}
Nested While Loop :
Nested While loop is While loop inside a While loop and so on which is used to run multiple loop conditions.
Syntax:
while (condition)
{
while (condition)
{
code to be executed if the condition is true;
}
}
Infinitive While loop :
Infinitive While loop is a While loop with condition 1 and thus running for infinite number of times.
Syntax:
while (1)
{
code to be executed;
}
Example of While loop
#include <stdio.h> void main() { int i = 1; while (i <= 10) { printf ("%d", i); printf ("\n"); i++; } } |
