Write a program that reads the R and C dimensions of a two-dimensional array T of type int (maximum dimensions: 50 rows and 50 columns). Fill in the array with values entered on the keyboard and display the array and the sum of all its elements.

#include<stdio.h>
#include<math.h>
#include<conio.h>
#define SIZE 50
void main()
{
	int A[SIZE][SIZE];
	int R, C; // dimension of the array
	int i, j; // counters
	int sum = 0;

	do {
		printf("Enter the number of rows: ");
		scanf("%d", &R);
	} while (R <= 0 || R > 50);

	do {
		printf("Enter the number of columns: ");
		scanf("%d", &C);
	} while (C <= 0 || C > 50);

	for (i = 0; i<R; i++)
		for (j = 0; j < C; j++)
		{
			printf("Enter A[%d][%d]=", i, j);
			scanf("%d", &A[i][j]);
			//sum+=A[i][j];
		}

	printf("\n\nPrinting the array\n");
	for (i = 0; i < R; i++)
	{
		for (j = 0; j < C; j++)
		{
			printf("%4d", A[i][j]);
			//sum += A[i][j]; // correct
		}
		printf("\n");
		//sum+=A[i][j]; // WRONG because j will be equal to C
		// A[i][C] will be out of bound 
	}

	for (i = 0; i<R; i++)
		for (j = 0; j < C; j++)
			sum += A[i][j];


	printf("Sum=%d\n", sum);


	getch();
}
