4. Here are two source files main.cpp and area.cpp, intended to be linked together into a single program. * main.cpp #include #Include -area . h- int main() f using std::cout; using std: :endl; using std: :cin; cout > w >> h; cout

Explanation / Answer

4)The file area.h should include the both functions declarations so like below we declare a function in c++:

#ifndef area // this is the pragma

#define area // and the guard

float get_tri_area(float a, float b);

float get_rect_area(float a, float b);

#endif
