using a while loop.

#include <stdio.h>
#include <stdlib.h>

main()
{
   int menu;
   printf("1.Test1\n");
   printf("\n2.Test2\n");
   printf("\n3.Exit\n");
   printf("\nEnter Selection: ");

   scanf("%d", &menu);

   while (menu!=3)
   {
       switch(menu)
       {
           case 1:
              system("cls");
              printf("Test1\n");
              break;
           case 2:
              system("cls");
              printf("Test2\n");
              break;
        }
         scanf("%d", &menu);	
    }
			
   return 0;
}

Are there any other method beside using while loop ??


thx in advance

a do-while loop ;p

There are three types of loops:

while( condition )
{
    do all of this
}

This has the potential to not ever be executed, if the condition evaluates to false initially.

do
{
    do all of this
} while( condition );

This loop will always execute the contents of the body of this loop at least once, even if condition evaluates false when it reaches there.

for( initializers; condition; usually-[ de ][ in ]crementing )
{
    do all of this
}

This loop could also potentially never execute the body of the loop. In this loop, any or all of the elements of this loop may be left out. ( Meaning, you can not use the initialization portion, the check, or any incrementing / decrementing. They're all optional. )

These are the three standard methods of looping.

but goto's are the best

ok. i get it.
Thanks a lot quzah.

but goto's are the best

That's why I said these are the three standard methods of looping.
