do while loop in c
- The last of C’s loops is the do-while. Unlike the for and the while loops, in which the condition is tested at the top of the loop, the do-while loop checks its condition at the bottom of the loop.
- This means that a do-while loop will always execute at least once.
- Unlike for and while loops, which test the loop condition at the top of the loop, the do...while loop in C programming checks its condition at the bottom of the loop.
Syntax:
do
{
statement(s);
}
while(condition);
Flow Diagram for do while loop:
Example:
#include <stdio.h>
int main()
{
int j=0;
do
{
printf("Value of variable j is: %d\n", j);
j++;
}
while (j<=3);
return 0;
}
Output:
Value of variable j is: 0 Value of variable j is: 1 Value of variable j is: 2 Value of variable j is: 3
