// Program: Transpose of a Square Matrix

// Topic: 2D Arrays and Matrix Manipulation

// Description: Reads an m×m matrix from user input and computes its transpose by interchanging rows and columns.

// Demonstrates use of nested loops for matrix traversal and creation of a new transposed matrix.
