MATRIX CALCULATOR Design a Matrix Calculator in C that performs matrix addition, subtraction, scalar multiplication and matrix multiplication using User Defined Functions. The user should be able to choose the operation they want to perform from a menu that loops. The User Defined Functions are given with each menu operation below. Matricies can be of any size, but your program needs to test for operation size errors. If the operation cannot be done, print an error message Menu idea: MATRIX CALCULATOR Enter an operation: Associated User Defined Function 1- Add two matricies 2-Subtract two matricies 3 - Scalar Multiply one matrix 4- Multiple two matricies void matrixAddSub (int arroy1[10][10J, int array2[10](10L etc) uses same User Defined Function above void matrixScalarMultiplyfint array1[10)[101, etc) void matrixMultiply (int arroy1 [10|[10], int array2[101[10]. et (message if 1 to 4 not entered You must also include User Defined functions for a readMatrix and a printMatrix void readMatrix(int array1[10][10], int rows, int columns) void printMatrixfint array1[10]/10], int rows, int columns) Test Cases I 3-2] [5 2-11 16 5-3 42 3 +3 1 273s -1 5 4][43-2] L3 8 2] 4 23 -2 4 Error Message: Size Error -cannot subtract.
