/**
 * @file matrixCalculation.c
 * 53. Write a program to perform manipulation of matrix using different module as follows -
Addition () -> to make addition of two matrix
Subtraction () -> to make subtraction of two matrix
Multiplication () -> to multiply two matrices
Transpose () -> to transpose the 1st matrix
Print () -> print any matrix
