Second part of program not running no errors.

joker944 (1)
When I run this program it allows me to input the values but stops after that. I cant figure out why it does not run the output to show the results. I do not get any errors while debuging.

this is the program I am trying to do.
a. There are two quizzes, each graded on the basis of 10 points. b. There is one midterm exam and one final exam, each graded on the basis of 100 points. c. The final exam counts for 50% of the grade, the midterm counts for 25%, and the two quizzes together count for a total of 25%. (Don’t forget to normalize the quiz scores. They should be converted to a percentage before they are averaged in.)
Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of 70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and any grade below 60 is an F. The program will read in two exam scores as well as the student’s average numeric score for the entire course and final letter grade. Define and use a structure for the student record.
Data for the test run: 1 7 10 90 95 2 9 8 90 80 3 7 8 70 80 4 5 8 50 70 5 4 0 40 35

You never call any of your functions from main. You have user input the data and then you do nothing so the program ends.
