did not find EOF Pset 1 mario. expected "##\n", not " ##\n"
In case of a height of zero (which is a valid height), your programme should print zero lines and exit. You probably reject zero as a height and ask again, the tester doesn't expect being prompted for ...

cs50 pset1 mario math wrong or order?
There's a couple of problems.
First, height is essentially a constant after it is entered by the user. It represents the number of rows to print, and as such, shouldn't be changed by the program. It ...

Which loop can be replaced for nested for loops for PSET 1 (Mario More Comfortable)?

Pset 1 - Mario pyramid trouble with spaces/dots
The problem is your nesting of loops. For each row, you print height-row+1 dots/spaces and one hash, and this whole thing row+1 times.
Place your two inner loops on the same level, one after the ...

tests give weird results despite (seemingly) correct output
This expected "# #\n", not " # # \n" is telling you that there is an extra space in front and an extra space at the end.
There should be nothing printed after the final # on a line, so that part ...
