C Programming

EXERCISE C16
Write a C program incorporating a function to add all elements of a two dimensional array. The number of rows are to be passed to the function, and it passes back the total sum of all elements (Use at least a 4 x 4 array).


	#include <stdio.h>

	int add2darray( int [][5], int );	/* function prototype */

	int add2darray( int array[][5], int rows )
	{
		int total = 0, columns, row;
		
		for( row = 0; row < rows; row++ )
			for( columns = 0; columns < 5; columns++ )
				total = total + array[row][columns];
		return total;
	}

	main()
	{
		int numbers[][] = { {1, 2, 35, 7, 10}, {6, 7, 4, 1, 0} };
		int sum;

		sum = add2darray( numbers, 2 );
		printf("the sum of numbers is %d\n", sum );
	}
