I need help in my c++ program HW (c++ codes please)

Design and code a program which outputs a numeric grade and a letter grade. The numeric grade is a score 0-100. The letter is based on the numeric grade according to the following scale: Your program will read a test score (this can be any integer value) and the max number of points for the test(agaia any integer value). It must then convert the test grade to a value 0-100 and determine the letter grade corresponding to that value. Your program should repeat the process for 12 test grades and test points if test score is 35 and max test points are 45, the numeric score (based on 100) is 77.77 and the letter grade is C if test score is 22 and max test points are 25, the numeric score (based on 100 is 88 and the letter grade is B if test score is 100 and max test points are 200, the numeric score (based on 100 is 50 and the letter grade is F
