Mario pyramid works, but check50 not buying it

This code prints too many ...

MarioLess - declaration shadows a local variable error
Look at this code:
int h = get_positive_int("What height do you want: ");
//print the pyramid
for (int h = 0; h < n; h++)
It declares h (as an int) twice. Change one of them.
Also, n hasn't ...

Stumped on PSET 1 Mario Less Comfortable
Looks like you have an extra for loop there, which will cause the entire thing to loop l times when that's probably not what you intended.

A problem with my code in PSET 1 Mario less comfortable
The problem is in your nested for loop. It prints a space all the way up until i + j <= n - 1. Once this is no longer true, your program exits the loop.

PSet 1 Mario Less - cube instead of expected stair
The inner for loops are all based on height, so they're going to do exactly the same thing on every pass of the outer loop. Every row will look like every other row, so you get a cube.

Think negatively!
Look at the test that the code is doing:

This checks that n is in the range that is valid. You want the loop to repeat if it isn't in the ...
