Part 2(70 points)Write a C program (with meaningful comments) to solve a problem described in English. We want to count how many passing grades are entered. We don't know how many grades there will be. Use a sentinel controlled while loop that will ask the user to enter student grades until a value of 1 is entered. Use a counter variable to count all the grades that are passing grades, where 70 is the minimum passing grade. If there are any grades that out of the range 0100, present an error message to the user, and do not count that grade as passing. We also would like to see what percentage of the valid grades Create two more test cases. Use following one in addition to the you create. ides. 80.0% of the valid grades entered are passing grades. Deliverables: Paste code, program output and screen shots into one Word document. Presenting your solution is part of the assignment. 1. Solution to Part 1(paste code and screen shot/s of the output window) - the relational/logical expressions. (20 points) 2. The code that solves the passing grades problem. Remember to use meaningful comments. (70 points) 3. Output from running the program 3 different times. Use two test cases that you created and the one I have given you. (10 points)
