Sumofmatrics.cpp

/*
This C++ program add two matrices i.e. compute the sum of two matrices and then print it.
Firstly user will be asked to enter the order of matrix ( number of rows and columns )
and then two matrices. For example if the user entered order as 2, 2 i.e. two rows and
two columns and matrices as
First Matrix :-
1 2
3 4
Second matrix :-
4 5
-1 5
then output of the program ( sum of First and Second matrix ) will be
5 7
2 9
