Thread: Two-dimensional array

I really need help with this problem. I am not even sure where to start. Thank you in advance

• Write a C program that uses a 2-dimensional (2D) array.
• Use the word “array” as the array identifier
• Define the size of the array as 10x10
• Use for loop(s) to assign the following values to each of the array elements.

• Use for loop(s) to print the array in a nicely aligned table, as shown in picture above.

We cannot and will not do your homework for you. Your instructor should have given you enough information you need in order to complete the assignment.

Please see the Homework Guidelines for the site.

One you have a first cut of the code, and present it here in Code Tags, then feel free to ask us specific questions.

I was not asking for you to do it for me. Just some assistance to point me in the right direction

This is what I have so far. As i have stated before I do not want you to do it for me just some help.

Code:

#include<stdio.h>


int main()
{
	int a[10][10], i , j, r, c;


	for (i = 0; i < 9; i++) 
	{
		for (j = 0; j < 9; j++)
		
	}


	for (r = 0; r < 9; r++)
	{
		for ( c = 0; c < 9; c++)
		{
			printf("\n[%d]", a[i][j]);
		}
	}
	return 0;
}

	return 0;
}

What is your output?

What do you think the problem is?

I did forget the equation for the first for loop to assign the variables. Here is what I have.

Code:

#include<stdio.h>


int main(void)
{
	int a[10][10], i , j, r, c;


	for (i = 0; i <= 9; i++) 
	{
		for (j = 0; j <= 9; j++)
		a[i][j] = i;
	}


	for (r = 0; r < 9; r++)
	{
		for ( c = 0; c < 9; c++)
		{
			printf("\n[%d]", a[i][j]);
		}
	}
	return 0;
}

Here is the output I am getting
