Syntax for Function Prototyping in Header Files

Question

Consider I have the following function prototype:

void MyFunction(int MyParameter);

With the following definition:

void MyFunction(int MyParameter)
{
    // Do stuff here.
}

Where should they each be put if I have a header file (no main function) with a namespace? Does the prototype go in the namespace and the definition outside it? Or do they both go in?

Answer 1

If you choose to have a namespace, both should be inside :

.h :

namespace MyNameSpace {
void MyFunction(int MyParameter);
}

.cpp :

void MyNameSpace::MyFunction(int MyParameter)
{
    // Do stuff here.
}
