/* This is a program to demonstrate the creation, assignment and use of a matrix of function pointers... One can pass any function in assign which accepts two integers and returns one. Currently, 4 basic operation functions have been defined for use, all the user needs to do is enter two numbers (unsigned ints), into the input box and the program shall display the result from the four functions...
