Hey I just started learning some C++ programming from the tutorials provided by this website, and I'm trying to make a simple calculator. This is what I have but I'm getting build errors, can anyone help me? I can't seem to find what's wrong.
Code:
#include <iostream>
using namespace std;
int mult ( int x, int y );
int add ( int x, int y );
int div ( int x, int y );
int sub ( int x, int y );
int main()
{
int x;
int y;
int option;
cout<<"1 - Add\n2 - Subtract\n3 - Multiply\n4 - Divide";
cin>> option;
cin.ignore();
if ( option == 1 )
{
cout<<"Input the numbers you would like to add.\n";
cin>> x >> y;
cin.ignore();
cout<<"The sum is: "<< add ( x, y ) <<".\n";
}
else if ( option == 2 )
{
cout<<"Input the numbers you would like to subtract.\n";
cin>> x >> y;
cin.ignore();
cout<<"The difference is: "<< sub ( x, y ) <<".\n";
}
else if ( option == 3 )
{
cout<<"Input the numbers you would like to multiply.\n";
cin>> x >> y;
cin.ignore();
cout<<"The product is: "<< mult ( x, y ) <<".\n";
}
else if ( option == 4 )
{
cout<<"Input the numbers you would like to divide.\n";
cin>> x >> y;
cin.ignore();
cout<<"The quotient is: "<< div ( x, y ) <<".\n";
}
cin.get();
}
int add ( int x, int y )
{
return x + y;
}
int sub ( int x, int y )
{
return x - y;
}
int mult ( int x, int y )
{
return x * y;
}
int div ( int x, int y )
{
return x / y;
}
