Sum of all elements in a two dimensional array. In C, You can not use a pointer to int to map a 2D array, should be: int matrix_sum (int data [] [4], int rows) { int x = 0; //sum of all elements for (int i = 0; i < rows; i++) //loop for row { for (int j...
Can I use the SUM function to add together the elements of a matrix? Yes, in many programming languages, you can use the SUM function (or an equivalent) to add together the elements of a matrix. However, the process might involve flattening the matrix into a single list or array of num...
