Hello! I am trying to write a program that has three files, two .cpp and one .h
one of the .cpp files is details the function for the .h and im having trouble getting it to compile. I know it has to do with using return and i dont know how the code shoud look.
Below is the functions .cpp

#include "figures.h"

int filledSquare(int a)
{
	for  (int b = 0; b < a; b++)									//first figure
	{
		for (int c = 0; c < a; c++)
			cout << "*";
		cout << endl;
	}
	cout << endl;
}
int leftTriangle(int a)
{
	return (int b = a; b > 0; b--)									//second figure
	{

			cout << "*";
		cout << endl;
	}
	cout << endl;
}
int rightTriangle(int a)
{
return (int b = 0; b < a; b++)									//third figure
{
	int s = a - b;                                            //calculates number os stars to print
	for (int c = 0; c < b; c++)
		cout << " ";
	for (int c = 0; c < s; c++)
		cout << "*";
	cout << endl;
}
cout << endl;
}
int hollowSquare(int a)
{
return (int b = 0; b < a; b++)									//fourth figure
{
	int s = a - 2;
	if (b == 0 || b == (a - 1))

I changed the function .cpp so that there is no return on each function. So now the only errors im receiving are from those functions not returning a value. I'm not sure how to write that part in the functions themselves.

Shameless self bump, really stuck on this. Also i believe that for choosing a filled or hollow square, i do not have the correct code to have the user enter f for filled or h for hollow.
