Write a complete C program to perform Matrix operations such as Addition, Subtraction, Multiplication and Transpose according to the user’s choice. The program should display the following menu to the user for them to select one of the five options listed.

------------------
MAIN MENU
------------------
1. MATRIX ADDITION
2. MATRIX SUBTRACTION
3. MATRIX MLTIPLICATION
4. MATRIX TRANSPOSE
5. TO EXIT
---------------------------
Please enter your option <1/2/3/4/5>:

The program should ask the elements of the input matrix or matrices from the user once the required operation is selected. The program should produce a neat output showing both the input and the resultant matrix in matrix form. The program should not be terminated until the user selects the option number 5 (TO EXIT).


THIS IS THE PROGRAM I HAVE DONE.. URGENT PLEASE CORRECT FOR ME! THANKS A LOT!!!!
