c multiplication table and sum of all values

[Darkroman]

I made this program after some trial and error and learning about two dimensional arrays. Is there another, perhaps more elegant way to write this program, I can put down the condition statements later, but anyway here's the code

#include <stdio.h>

int i = 0;
int j = 0;
int SIZE;
int sum;

int
main(void)
{
	printf("Enter a number for its multiplication number ");
	scanf("%d", &SIZE); // SIZE will determine the size of the array

	int array[SIZE][SIZE]; //Initialize array after user inputs a number

	for (i = 0; i < SIZE; i++)
	{

		for (j = 0; j < SIZE; j++)
		{
			array[i][j] = (i + 1) * (j + 1); // This will mutliply the rows and columns together each loop count

			printf("%4d", array[i][j]); // Prints the array value done by above equation
		}
		
		printf("\n");
	}
	printf("\n");

	for (i = 0; i < SIZE; i++)
	{
		for (j = 0; j < SIZE; j++)
		{
			printf("array[%d][%d] is %d\n", i, j, array[i][j]); // Prints out where the loop is in the array and the value in said element
			sum += array[i][j]; // Loop goes through and saves the values in sum while adding from the last value of sum each loop count

		}
	}
	
	printf("\nThe sum of all numbers is %d\n\n", sum); // Output of total sum

	return(0);
}

You can probably reduce it to a simpler form

#include <stdio.h>

int i = 0;
int j = 0;
int SIZE;
int sum;

int main(void)
{
        printf("Enter a number for its multiplication number ");
        scanf("%d", &SIZE); // SIZE will determine the size of the array

        int array[SIZE][SIZE]; //Initialize array after user inputs a number

        for (i = 0; i < SIZE; i++)
        {

                for (j = 0; j < SIZE; j++)
                {
                        array[i][j] = (i + 1) * (j + 1); // This will mutliply the rows and columns together each loop count
                        sum += array[i][j]; // Loop goes through and saves the values in sum while adding from the last value of sum each loop count

                        printf("%4d", array[i][j]); // Prints the array value done by above equation
                }

                printf("\n");
        }
        printf("\nThe sum of all numbers is %d\n\n", sum); // Output of total sum
        printf("\n");
        return(0);
}
