          {

case 1:

printf("Sunday");

break;

case 2:

          Friday

Program 3

#include

#include

void main()

{

int choice,x,y;

clrscr();

          printf("\n\t\t\t Calculator Program");

          printf("************************************");

          printf("Enter 2 number\n");

          scanf("%d%d",&x,&y);

          printf("\n 1. Addition of 2 nums");

          printf("\n 2. Subtraction of 2 nums");

          printf("\n 3. Multiplication of 2 nums");

          printf("\n 4. Divition of 2 nums");

          printf("\n Enter your choice from(1to 4) ");

          scanf("%d",&choice);

          switch(choice);

          {

          case 1:

          printf("%d+%d  is = %d",x,y(x+y));

          break;

          case 2:

          printf(" %d - %d is = %d",x,y(x-y));

          break;

          case 3:

          printf(" %d * %d is = %d",x,y(x*y));

          break;

          case 4:

          printf("%d / %d is = %d",x,y(x/y));

          break;

          default:

          printf(" Invalid input enter between ( 1 to 4) only");

          }

getch();

}

Output
