How do I write a recursive function in C++ to display a triangle of* like this:
*

I am able to write a recursive function to display an inverted triangle like this:

**
*

 
The code for the inverted triangle function is:

void inverted(int a) { if (a==1) {cout<<"*"<<endl; } else { for (int i=0; i<a; i++) {cout<<"*"; } cout<<endl; inverted(a-1); } }

 
I am allowed to use a loop (e.g. for loop) to print a row of * but I must use
a recursive function to control the number of rows.

For the uninitiated, a recursive function is a function that calls itself.

Please, provide some insight into the problem.
