This C Program finds the sum of each row & each column of a MxN matrix. The program accepts an MxN matrix. Then adds each row of the matrix and also adds each column of the matrix.

Here is source code of the C program to find the sum of each row & each column of a MxN matrix. The C program is successfully compiled and run on a Linux system. The program output is also shown below.
