3. Write a macro that carries out the following. (a) Creates a 4 by 4 matrix A with aij = i + j and writes the result to cells A1:D4. (b) Creates a 4 by 4 matrix B with bij = 1²-j² and writes the result to the cells G1:J4. (c) Calculates the matrix C = A(B-21), where I is the identity matrix, and writes the result to cells A6:D9. Declare all variable types and include appropriate comments in your code.

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2.

Create a program code that reads five integers from the keyboard, assign them to the elements of a one-dimensional array with a loop, and then print the smallest and largest elements of that array on the screen. Perform the task of finding the smallest and largest elements. This function should take the array, using pointers to assign the smallest and largest valued elements of the array (ie input parameters will be three points). This function will find the smallest and largest elements of the array. It will assign it to variables sent to it, and it will not return any value to the calling function. Writing the values to the screen must be done within the main () function.
