if(ch<=5 & ch>0)
{
printf("Enter two numbers:\n");
scanf("%d%d",&a,&b);
}

switch(ch)
{
 case 1:
 res=a+b;
 printf("\n Addition:%d",res);
 break;

 case 2:
 res=a-b;
 printf("\n Subtraction:%d",res);
 break;

 case 3:
 res=a*b;
 printf("\n Multiplication:%d",res);
 break;

 case 4:
 res=a/b;
 printf("\n Division:%d",res);
 break;

 case 5:
 res=a%b;
 printf("\n Remainder:%d",res);
 break;

 case 0:
 printf("\n Choice Terminated");
 exit();
 break;

 default:
