Code Completion Challenge - Calculator Challenge Solution

Calculator Challenge Solution

The following program will function as a basic calculator; it will ask the user to input what type of arithmetic operation he would like, and then ask for the numbers on which the operation should be performed. The calculator will then give the output of the operation.

#include <iostream>

int multiply(int x, int y) { return x*y; }

int divide(int x, int y) {
return x/y;
int add(int x, int y) { return x+y; }
int subtract(int x, int y) {
return x-y;

using namespace std;

int main()
char op='c';
int x, y; while(op!='e')
{ cout<<"What operation would you like to perform: add(+), subtract(-), divide(/), multiply(*), [e]xit?"; cin>>op; switch(op) { case '+': cin>>x; cin>>y; cout<<x<<"+"<<y<<"="<<add(x, y)<<endl; break; case '-': cin>>x; cin>>y; cout<<x<<"-"<<y<<"="<<subtract(x, y)<<endl; break; case '/': cin>>x; cin>>y; cout<<x<<"/"<<y<<"="<<divide(x, y)<<endl; break; case '*': cin>>x; cin>>y; cout<<x<<"*"<<y<<"="<<multiply(x, y)<<endl; break; case 'e': return 0; default: cout<<"Sorry, try again"<<endl; }
} return 0;
