Magic Square Checker 🌟🔍
Overview 📖
This C program checks if a given square matrix is a “Magic Square”. A Magic Square is a square grid filled with distinct integers such that the sum of numbers in each row, column, and both main diagonals is the same.
This program was created as part of the Systems Programming 20465 course in the 2022a semester at The Open University of Israel and achieved a perfect score. 🎓🌟
Features ✨
- Input Validation: Ensures only valid integers are entered.
- Matrix Creation: Dynamically generates a square matrix based on user input.
- Magic Square Verification: Checks if the matrix is a magic square.
- User-Friendly: Provides clear instructions and feedback.
How to Use 🛠️
- Enter Matrix Size: You will be prompted to enter the size of the square (1-9).
- Fill the Matrix: Enter the required number of integers to fill the matrix.
- Magic Square Check: The program will then evaluate if the matrix is a magic square and display the result.
