Question: Define a function that takes two input parameters, a vector of test scores and a scalar passing grade. The function returns the fraction of passing grades as a number in the range [0 1] (so 0.3 means 30% of the grades were passing. Define the function without using any MATLAB library functions.
Write a main program that prompts the user to enter grades in a loop, ending on a negative number, stores the grades in a vector, and asks the user for a passing grade. Ten pass the grade vector and passing cutoff to the function and print the percent of passing grades.
