The goal of this HW is to write a C program that prints the final letter grade after the user is asked to enter the average scores for HW$,$ Project, Lab, Midterm$1,$ Midterm$2$ and the Final Exam. Well use our Syllabus grading rubric $($provided below$).$ All the average scores are to be declared as float variables. $-$ Online HWs : $20\%-$ Online Projects : $20\%-$ In Person Labs : $5\%-$ Online Exams $($Lockdown Browser with WebCam$)($two midterms and a final$)$: $55\%$ LetterRange $(\%)$A$94100$A$-9093$B$+8789$B$8486$B$-8083$C$+7779$C$7476$C$-7073$D$+6769$D$6466$D$-6163$F$0-60$ Pay close attention to the sample runs below. The user is allowed up to three times to enter a valid score. All scores are real numbers that are between $0$ and $100.$When the program prints the final letter grade, the user $($see sample runs below$)$ is asked to start over by entering either y or Y$.$ An entry that is different from y$,$Y$,$n and N is cosidered invalid. The user will be allowed to try up to $3$ times to enter either y$,$Y$,$n or N$.$
