How to create isoceles triangle in C++

Can anyone help me implement a isoceles triangle program code in C++.

I am trying to create a isoceles triangle in C++ made out of asterisks using int n and a for loop

*n must be > 0

*Prints an isosceles triangle (pointing up)

* where parameter n is the height

* prints an endl at the end of each row

* Note: no spaces at the end of lines

* n represents number of rows and changes with user input (user inputs number of rows)

* 1.. 3.. 5... 7... 9 asteriskis (increase by odd numbers for each row)
