(2) lowest score drop program write a modular program that calculates the average of a group of test scores, where the lowest score in the group is dropped. it should use the following functions: void getscore ( ) should ask the user for a test score, store it in a reference parameter variable, and validate that it is not lower than 0 or higher than 100. this function should be called by main once for each of the five scores to be entered. int findhighest ( ) should find and return the highest of the five scores passed to it. it should be called by main, and should include an appropriate display statement to indicate the highest score. void calcaverage ( ) should calculate and display the average of the four highest scores. this function should be called just once by main and should be passed the five scores. int findlowest ( ) should find and return the lowest of the five scores passed to it. it should be called by calcaverage, which uses the function to determine which one of the five scores to drop. *note: all of the above functions will need parameters, they are just not listed here. do not use an array. input validation: do not accept test scores lower than 0 or higher than 100.
