Question

C++

4. Write a function named calculate ( ) that has two integer numbers parameter named x and y and char parameter named operator. The passed char represents a type of mathematical operation such as “+” “ -” “ *” “ /” . your function should apply the corresponding mathematical operation on integers X and y . and return an integer result . make sure your main ( ) will ask the user to input data, call the function , and display the result . test the function by passing various data to it .
Hint: the function prototype can be int calculator(int, int,char).

Explanation / Answer

#include<iostream>

using namespace std;

int calculator(int, int,char);

int main(){
  
   int x, y;
   char op;
  
   cout<<"Enter value of x and y : "<<endl;
   cin>>x>>y;
   cout<<"Enter operator (+,-,*,/) : ";
   cin>>op;
  
   int result = calculator(x,y,op);
  
   cout<<"Result: "<<result<<endl;
   return 0;
   }

int calculator(int x, int y,char op){
   int result = 0;
   switch(op){
      
       case '+':
               result = x+y;
               break;
       case '-':
               result = x-y;
               break;
              
       case '*':
               result = x*y;
               break;
       case '/':
               result = x/y;
               break;
       default:
               cout<<"Invalid operator"<<endl;
       }
   return result;
   }

/*

Output:

Enter value of x and y :
3
4
Enter operator (+,-,*,/) : +
Result: 7
