Write a program in C that recreates a half-pyramid using hashes (#) for blocks. Prompt the user for the half-pyramid’s height and align the bottom-left corner of the half-pyramid with the left-hand edge of the terminal window.

Thanks, worked like charm.
(hash = 1; hash <= (all_rows + 1); hash++)
if you set int hash equal to 0 instead of one, you don't have to set the limit to all_rows +1
please am new to programming. can some one explain to me the above program and how the for loops work
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
For the initialization and conditions of the nested for loops, why subtract height by row? Also what will the original “all_rows” loop do?
Thanks for posting this. But please also explain in steps because we are new to these kind of projects,
Maybe you should take Intro to computer Science? You take it free here: https://prod-edx-mktg-edit.edx.org/course/introduction-computer-science-harvardx-cs50x
can you please explain
for (hash = 1; hash <= (all_rows + 1); hash++)
I am taking this class Harvard CS50 online, I wanted some commentary on my loops. However after reading your code. I would appreciate some information on your Mario For loop.
would you consider consulting this violating academic honesty?
this class is really hard I feel like i can’t do it without consulting outside sources
I regret saying that I gave up developping this code on my own (it’s my first week programming) and copied-pasted yours. Why does it always tell me (in mine) that I have one single error: “mario2.c:7:1: error: expected identifier or ‘(‘ “?? How can I check it?
