PROGRAM A:

Design a program in C which computes and outputs to the console a two-dimensional array each of whose elements is the triangular number tNo of the corresponding element of the following user-supplied two-dimensional array of positive integer numbers:

x[3][4] = {{1,2,3,4},{5,6,7,8},{9,10,11,12}}

In your design, you are to use a prototype function called triangular which is to be placed after the main function, with outputting to the console also done from the prototype function.

PROGRAM B:

Modify PROGRAM A above so that, for the same given input array x[3][4], the new program will now also output to the console another two-dimensional aray each of whose elements is the factorial of the corresponding element of the x[3][4] array. In your design, you are to use a prototype function called factorial which is to be placed before the main function, with outputting to the console also done from the prototype functon.
