The basic format of the do-while loop statement is:

Syntax:

Example of a C Program to Demonstrate do-while loop

Example:

#include<stdio.h>
 
int main ()
{
   /* local variable Initialization */
   int n = 1,times=5;

   /* do loops execution */
   do
   {
       printf("C do while loops: %d\n", n);
       n = n + 1;
   } while( n <= times );
 
   return 0;
}
