It is also called as post tested loop. It is used when it is necessary to execute the loop at least one time. Syntax:

do {
Loop body
} while (Expression);

Example:

int main(){
    int num,i=0;  
    do{
         printf("To enter press 1\n");
         printf("To exit press  2");
         scanf("%d",&num);
         ++i;
         switch(num){
             case 1:printf("You are welcome\n");break;
             default : exit(0);
         }
    }
    while(i<=10);
    return 0;
