Question
It is required to write a Matrix Calculator program using C Programming Language that could only perform addition, subtraction, and multiplication of two matrices of appropriate dimensions. Your program should enable the user to select a matrix operation from a list of options that contain the aforementioned operations. Then, the user should be prompted to enter the dimensions of the two operand matrices (use input validation loop to make sure that the user entered approximate matrix dimensions for the selected operation). Next, your program should prompt the user to enter the elements of each matrix row-wise. Your program should perform the selected matrix operation on operand matrices and display the result on the console.
