I'm still trying to get to grips with C++ and I understand the idea and use of header files, but every time I try and implement one I get the same error every time
Undefined symbols for architecture x86_64:
"Maths::addnumber(int, int)", referenced from:
_main in main-3adee4.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
I'm just trying to make it work at the minute with just a very basic add method just to actually make a header file work really but no matter what I've read so far I can't seem to fix it. Any help would be amazing thanks!
This is my tester.cpp
#include "tester.hpp"
using namespace std;
int Maths::addnumber(int x, int y)
{
int ans = x + y;
return ans;
}
This is my tester.hpp
#ifndef tester_hpp
#define tester_hpp
#include <stdio.h>
class Maths
{
public:
int addnumber(int x, int y);
};
#endif /* tester_hpp */
This is my main.cpp file
#include <iostream>
#include "tester.hpp"
using namespace std;
int main()
{
Maths test;
test.addnumber(10,20);
return 0;
}
