A, B, C, and D are two-dimensional arrays , all of the same size ,and all of type  double . I need code fragment that computes D = A + B + C, where each element  of D is the sum  of the corresponding elements  of A, B and C. Also  two integer  variables  numRows and numCols that denote the number of rows and columns in each matrix.

Did you try attempting the question?

Two for loops will do the trick.

Until you try to solve the problem, and post your code here, we don't help with homework problems. That said, ddanbe is correct (hint)... :-)
