I am new to C++ and I am creating a very simple program using classes. I am using Visual Studio Code to write my code and MinGW compiler to build and run it. I have written the following code as an example to show my problem.
Main.cpp
#include "class.h"
using namespace std;
int main(void) {
myClass myObject;
myObject.sum(10, 20);
return 0;
}
class.h
#pragma once
class myClass{
public:
void sum(int a, int b);
};
class.cpp
#include <iostream>
#include "class.h"
using namespace std;
void myClass::sum(int a, int b) {
cout << "The sum = " << a + b << endl;
}
The compiler is giving me this error when I try to build it.
undefined reference to `myClass::sum(int, int)' collect2.exe: error: ld returned 1 exit status
BTW I know there are a lot of similar questions on the forum and I am sorry I am posting it again but all those solutions didn't seem to work for me as my program here is pretty simple. Any help will be very appreciated. Thanks!
