A. Consider the following statements int *ptr-num, num; State whether the above statements are valid or invalid. Justify your answer. B. Write a C program to read elements into an MxN matrix and display the elements. The elements of the matrix can be up to a three (3) digit number. Extract all two-digit and three- digit numbers from the input matrix, compute the sum of squares of individual digits, and store the sum in a 1D array and display the resultant array. Sample Matrix and output: Enter the order of the matrix 23 Matrix elements: 567 12 4 23 345 6 Resultant 1D array: 110 13 5 50 A.
