I am having difficulty understanding functions and how to write a program using one. Foe example, I need to write a program that takes a number from the user and prints a diamond.
I need to use functions to tell the program hoe many spaces to print and how many * to print. Can any one hellp me please?
Thanks
for functions read some tuts. It will click soon. They are not hard to understand especially when you see them working. As for the other its been done about a zillion times now in all sorts of fancy ways ( well by prelude anyway ). Im certain a board search will be all you need to do your homework.
Free the weed!! Class B to class C is not good enough!!

Hi,
Here is an example program which calls a function:
Code:#include <iostream> using namespace std; void DoubleThenPrint(int a) { cout<<2 * a<<endl; } int main() { int a = 4; DoubleThenPrint(a); return 0; }
how do I call the function to print both spaces and stars using the exact same function?
A function is just like a miniature program--you're not limited to one line of code. You can make the function do anything you want. It can be 10,000 lines long, and print every character possible in a representation of the Mona Lisa. If you want the function to print a space, then do this:
cout<<" ";
If you want your function to print an asterisk next to the space, then do this:
cout<<"*";
Like magic, your function will have printed a space and an asterisk
