(C++) CPP Programs - 27

27. Write a C program to read a matrix A (M*N) and to find the following using functions.
a) Sum of elements of each row.
b) Sum of elements of each column.
c) Find the sum of all the elements of the matrix. Output the computed results with suitable heading.

/* Sum of rows and coloumns*/
