Im new to programming and Im trying out some simple things with templates. I wrote a simple multiply function in an additional source file
#include<iostream>
template<typename T>
void Multiply(T a) {
std::cout << 3 * a << std::endl;
}
with a header file with the decleration
#pragma once
template<typename T>
void Multiply(T a);
If I try to compile this code I get a linking error, which makes sense to me because, if I understand correctly, the compiler cant compile the source code without knowing what T is. So my question is, why does my code work if I add #include "Multiply.cpp" to the header file? That doesnt make too much sense to me, but the code successfully compiles.
