Need full working source code for this:

In this assignment, you will develop a C++ program to input and find the average for quiz and assignment grades, then calculate the overall average and letter grade.

Requirements:

• Use variables of the appropriate type.
• Use accumulators and counters. 
• Use a "for" loop to input quiz grades for the user and total the four quizzes. (Quizzes are worth 10 points)
• Calculate and display the quiz average
• Use a while loop to input and total the eight assignments. (Assignments are worth 20 points).
• Calculate and display the average of the assignments
• As the grades are inputted, check to make sure they are not negative numbers or greater than their worth.
• Calculate the overall average. To do so add your quizzes and assignments totals and divide by possible points.
• Use setprecision to only show the integer portion of the percentage grade.
• Use a nested if-else statement to translate your percentage to a grade.
• Display the total of quizzes, assignments, percentages, and letter grade.
