PS1 Mario, prints out nicely but check 50 rejects

Question

I've got this code for the Mario assignement in pset1. It prints out OK in the shell, but check50 rejects it. Can anybody help me?

#include <stdio.h>
#include <cs50.h>

int main(void)
{
    // initialize variables
    int x, y,z;

    // Request to the user to enter a value
    do
    {
    printf("Please give me an integer between 1 and 23.  ");
    x = GetInt();     
    }
    // check if the value is in range
    while (x <=0 ||x>23);
    y = x -1;
    z = 1;


    for (int i =x; x>0; i--)
    {

        for (int i = 0;i < x;i++)
        {
            // this prints the spaces
            printf(" ");

        }


        for (int i = 1; i <= z; i++)
        {

            //this prints the #
            printf("#");

        }

        // this causes the line break
        printf("\n");

        // adjustment of variables
        x--;
        z++;
    }
    return 0; 
}

Answer 1

When given 3 as input, your program prints out: (I will replace spaces with 0s for simplicity, and # with "hashtag" because stack has some formatting thing with hashes.) 00hastag 0hastaghastag hastaghastaghastag

so

2 spaces, 1 hash
1 space, 2 hashes
no spaces, 3 hashes

Instead, it should be

2 spaces, 2 hashes
1 space, 3 hashes
no spaces, 4 hashes
