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(); }
