Program skips for cycle

Hi, I have the following exercise:
"Write a C language program that reads a sequence of positive numbers from the keyboard
and for each number, print the progressive sum. The program ends when you enter a number less than or equal to zero."

Here's what I made but It seems to skip the for cycles. Help?
Output:

somma_numeri_positivi.c:23:21: warning: format specifies type 'int *' but the
argument has type 'int (*)[i][j]' [-Wformat]
if ( scanf("%d",&numbers) == 0 )
~~ ^~~~~~~
somma_numeri_positivi.c:38:5: warning: expression result unused [-Wunused-value]
getc;
^~~~
2 warnings generated.
Input a sequence of 0 numbers
3 <-- My input
[Program ended]

Code:

---

#include <stdio.h>

Code:

---

int main(void)
{
    int i;
    int j;
    int n;
    int sum;
    int numbers[i][j];


    printf("input a sequence of %d numbers\n", n);
    for (j=0; j<n; j++)
    {
        printf("element %d: ", i);
        scanf("%d", &numbers[i][j]);
    }
    if ( scanf("%d",&numbers) == 0 )
    {
        for(i=0;i<n;i++)
        {
            sum = 0;
            for(j=0;j<n;j++)
            {
                sum = sum + numbers[i][j];
            }
            printf("sum: %d\t", sum);
        }
    }


    printf("Program end");
    getc;

}

> int numbers[i][j];
Since i and j are uninitialised, you've no idea whether you have a valid array.

> scanf("%d", &numbers[i][j]);
But your loop says j

> if ( scanf("%d",&numbers) == 0 )
So what were you trying to say here?

> getc;
Maybe you were trying to call getc();

You don't even need an array for this problem. Here's how I interpret the problem statement:

1. Read a number.
2. If the number is less than or equal to zero, end.
3. Print the running sum.
4. Repeat from 1.

Try converting that pseudo-code to C.
