Example of a Switch Case Program:

Q. Write a menu driven program in C, press 1 for addition and press 2 for subtraction between 2 number.

#include <stdio.h>

#include <conio.h>

main()

{

int a, b, c, ch;

printf(“Press  1 for Addition.”) ;

printf(“Press  2 for Subtraction.”) ;

printf(“Enter Your Choice”) ;

scanf(“%d”, &ch);

switch(ch)

{

case1:

printf(“Enter 2 Number:”);

scanf(“%d%d”, &a, &b);

c=a+b;

printf(“Addition Result %d”, c);

break;

case2:

printf(“Enter 2 Number:”);

scanf(“%d%d”, &a, &b);

c=a-b;

printf(“Subtraction Result %d”, c);

break;

default:

printf(“Wrong Choice”);

break;

}

getch();

}
