(a)Define a function fnMultiply that computes and returns the product of the type int element of its array input argument. The function should have a second input argument telling the number of array elements to use.

(b) Written a function that has two parameters--an M x N integer matrix, and an integer target value. The function should display the row and column subscripts of all occurrences of the target value.

(c) Written a program that can calculate the sum of three equality M x N sized matrices,[MatrixA] + [MatrixB] + [MatrixC]. Program Specifications: Create functions 1) to read the input data. 2) to perform the calculation and 3) to display the result.
