Function question!
Author
I have 2 functions, and I want them to be able to call to each other, but they''re inside the same .cpp file.
I''ll give an example of what I have and what I''d want to do..
void hi1()
{
cout << "how are you?";
hi2();
}
void hi2()
{
cout << "i am fine." << endl;
hi1()
}
hi2 works fine, but hi1 won''t work because it says hi2 wasnt declared or created yet....so how would i get past this problem??
Declare all the functions at the start of your cpp file, then create them further down.
Like this:
void hi1();
void hi2();
void hi1()
{
cout << "how are you?";
hi2();
}
void hi2()
{
cout << "i am fine." << endl;
hi1()
}
Be careful; This code will create an infinte loop.
Like this:
void hi1();
void hi2();
void hi1()
{
cout << "how are you?";
hi2();
}
void hi2()
{
cout << "i am fine." << endl;
hi1()
}

Hi. What you need is a function declaration. These are lines that tell the compiler that there is a particular function in the file and it should just wait to see it.
// declare hi1
void hi1();
// declare hi2
void hi2();
void hi1()
{
cout << "how are you?";
hi2();
}
void hi2()
{
cout << "i am fine." << endl;
hi1()
}
Now the code will compile and the program will run...forever! This code has no way to stop calling itself!

// declare hi1
void hi1();
// declare hi2
void hi2();
void hi1()
{
cout << "how are you?";
hi2();
}
void hi2()
{
cout << "i am fine." << endl;
hi1()
}

Damn it! Beaten to the punch again!
By the way ghostboy, aybe you should invest in a good c/c++ book.
