Q:-Write a Menu-Driven Program to perform a simple calculation in C programming
write a menu-driven program in c for a simple calculator. This is a very interesting program. In this program, we are going to create a menu using a switch case statement in c programming. So, before writing our program, let’s see the expected output first.
#include<stdio.h>
#include<conio.h>
void main()
{
int num1,num2,opt;
printf("Enter the first Integer :");
scanf("%d",&num1);
printf("Enter the second Integer :");
scanf("%d",&num2);
printf("\nInput your option :\n");
printf("1-Addition.\n2-Substraction.\n3-Multiplication.\n4-Division.\n5-Exit.\n");
scanf("%d",&opt);
switch(opt) {
case 1:
printf("The Addition of %d and %d is: %d\n",num1,num2,num1+num2);
break;
case 2:
printf("The Substraction of %d and %d is: %d\n",num1,num2,num1-num2);
break;
case 3:
printf("The Multiplication of %d and %d is: %d\n",num1,num2,num1*num2);
break;
case 4:
if(num2==0) {
printf("The second integer is zero. Devide by zero.\n");
} else {
printf("The Division of %d and %d is : %d\n",num1,num2,num1/num2);
}
break;
case 5:
break;
default:
printf("Input correct option\n");
break;
}
getch();
} Output
