Make Simple Calculator in C
To make a simple calculator in C programming which performs basic four mathematical operations, use the switch case to identify the
input operator to perform required calculation then display the result
C Programming Code to Make Simple Calculate
Following is a simple C program which is a menu-driven program based on simple calculation like addition, subtraction, multiplication
and division according to user's choice:

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
void main()
{
clrscr();
float a, b, res;
char choice, ch;
do
{
printf("1.Addition\n");
printf("2.Subtraction\n");
printf("3.Multiplication\n");
printf("4.Division\n");
printf("5.Exit\n\n");
printf("Enter Your Choice : ");
scanf("%c",&choice);
switch(choice)
{
case '1' : printf("Enter two number : ");
scanf("%f%f",&a,&b);
res=a+b;
printf("Result = %f",res);
break;
case '2' : printf("Enter two number : ");
scanf("%f%f",&a,&b);
res=a-b;
printf("Result = %f",res);
break;
case '3' : printf("Enter two number : ");
scanf("%f%f",&a,&b);
res=a*b;
printf("Result = %f",res);
break;
case '4' : printf("Enter two number : ");
scanf("%f%f",&a,&b);
res=a/b;
printf("Result = %f",res);
break;
case '5' : exit(0);
break;
default : printf("Wrong Choice..!!");
break;
}
printf("\n------------------------------------\n");
}while(choice!=5 && choice!=getchar());
getch();
}
When the above c program is compile and executed, it will produce the following result:
