This program creates a matrix of integers using user ipnut or file input. If user input is used, a single integer n will be used to create a matrix with n rows and n columns. If files are used to create the matrix, please ensure that the number of rows and columns are listed above the matrix. Ex. 3 3\n 15 24 26\n 35 62 59\n 75 48 69\n This is a matrix containing 3 rows and 3 columns.
