    Array

    Hi, I'm trying to create a two dimensional array that displays zeroes in a 10 by 10 format. But I don't really know how.
    I've been playing around and this is what I have so far:

    Code:
    #include<stdio.h>
    
    
    int main(void)
    
    
    {
    int my_array[10][10]={0};
    int i,j;
    
    
    for (i = 0; i < 10; i++)
    
    
        {
    
    
            for (j = 0; j < 10; j++)
    
    
                {
            printf("\n%d", my_array[i][j]);
             }
        
         }
        
    return(0);
    }

    Try
    printf("%d "
    inside the j loop

    and
    printf("\n") in the i loop

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Look up "Printf format specifications" for how to print a number using a certain field width
    Also, ask yourself, when do you need to print a newline?

    So I got the 30*30 matrix.

    But it's just a block of zeroes. How can I make it more presentable?

    How do you expect anyone to know what what you consider to be "presentable" unless you tell them. Mindreading?

    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Sunshine, and read this, this, and this before posting again.

    presentable= anything that doesn't just look like like a block of zeroes, whilst maintaining the 30 columns by 30 rows structure

    Have you looked into the advice given in post #3? If that's not what you're looking for, then you'll have to be more specific.
