Providing code in C++

#include <iostream>
using namespace std;

int main()
{
int a,b;
double result;
char operation;
cout<<"Enter the first integer: ";
cin>>a;
cout<<"Enter the second integer: ";
cin>>b;
cout<<"Enter the operation to be performed: ";
cin>>operation;
switch(operation)
{
case '+':
result=a+b;
cout<<a<<endl;
cout<<b<<endl;
cout<<operation<<endl;
cout<<result<<endl;
break;
case '-':
result=a-b;
cout<<a<<endl;
cout<<b<<endl;
cout<<operation<<endl;
cout<<result<<endl;
break;
case '*':
result=a*b;
cout<<a<<endl;
cout<<b<<endl;
cout<<operation<<endl;
cout<<result<<endl;   
break;
case '/':
if(b==0)
{
cout<<"error denominator cannot be 0"<<endl;
break;
}
result=(double)a/b;
cout<<a<<endl;
cout<<b<<endl;
cout<<operation<<endl;
cout<<result<<endl;   
break;
}

return 0;
}
OUTPUT:

Enter the first integer: 6
Enter the second integer: 5
Enter the operation to be performed: /
6
5
