write a c program for the above

Write a program to calculate a student's grade based on three test scores. Include a comment section at the top of your program with your name, date, and problem statement. In the program, prompt the user for three test scores, calculate the average, and then determine the grade using the algorithm below. If the average score is 90% or more, the grade is A. [f the average score is 70% or more and less than 9096, check the third score. If the third score is more than 90%, the grade is A; otherwise the grade is B. If the average score is 50% or more and less than 70%, check the average of the second and third scores. If the average ofthe two is greater than 70%, the grade is C; otherwise the grade is D. If the average score is less than 50% then the grade is F. . . . For maximum credit, implement the algorithm using nested statements within a given range rather than merely using all simple if statements. Within the selection structure, assign the grade to a character variable. Print the grade at the end of the program
