This program gets values from the user, and then runs a calculation. The values are passed by reference (by address), so the main() function sees the changed values of the variables. The first function (getValues(0) gets user input. The second function (calcCubic), performs the calculations, and the third function (printCubic)) prints the value of the calculation. Here is the code: #include char calculateLetterGrade (int numGrade) main () /Numerical grade to be entered / int numGrade. char grade, printf "What is your numerical grade? "); scanf (d", &numGrade) 10 11 grade cal culateLetterGrade (numGrade); printf /*Use function to determine 1etter grade* 12 13 ("nYour letter grade is tc\n", grade): L) 14 15 1 6 char calculateLetterGrade (int numGrade) 日( 17 18 char outputGrade: 1ぐ ifnumGrade>-90 && numGrade <100) 20 21 outputGrade A' else if numGrade>=8 && numGrade <89) outputGrade B' 66 numGrade <-79) else if numGrade>-7 outputGrade C' ; 35 66 numGrade <-69) else if numGrade>65 36 outputGrade D' ; 40 else 41 outputGrade F'; 42 43 44 return outputGrade; 4- And here is the output: RACIS126 CIS126 November 2018 Development Unit 3Unit 3 Guided Practice 6.exe What is your numerical grade?98 Your letter grade is A Process exited after 4.413 seconds with return value 0 Press any key to continue Submission Instructions Now, you enter the code, and run it.
