1) Array Initialize Suppose you wanted to pass in a matrix (2D array) to be initialized by a function to the identity matrix (Is on the diagonal, Os elsewhere). Make a function named identity that takes in a 2D array from main along with a size (assume a square matrix). (Hint: think about what issues occur and how you can get past them). Then make a function named display that again takes in a 2D matrix and size to print the array. Call this on the array after passing it into identity. Examples: What size matrix? 3 1 0 0 0 1 0 0 0 1
