//Program to understand the addition of two matrices. 
//while loop alert!!We spent this class demonstrating the perils of using the while loop namely 
//1.if the counter k characterizing the while loop is not incremented:
// expect to be stuck in the infinite loop FOREVER!
//2. if this while loop have 'expired' (k=0 k=1 and the while loop deems redundant)
// Find the product of two matrices.
