Void Functions

[computerquip]

in void rectangle (ofstream &fout, char ch , int x, int y), you call line completely incorrectly. 1) num isn't declared anywhere. 2) Your missing an entire parameter. And I don't understand why any of this matters. line() or rectangle() is never going to be called.

what do you mean by line() or rectangle() is never going to be called

[Bazzy]

You are not calling them in main

[thebeast]

something like this?

int main()
{
	ifstream fin;
	ofstream fout;
	fin.open("animals.dat");
	int i,j,y;

void line(ofstream &fout, char ch, int x);

void rectangle (ofstream &fout, char ch , int x, int y);
	for(int j=1; j=y; j++)
	{
		cout<<endl<<endl;
		cout<<endl<<endl;
	}
		return 0;
}

No, you should call them. Not declare them
