When you call the function, it should generate a random number in the range of 1 through 2. If the random number is 1, the function should display "heads". If the random number is 2, the function should display "tails". Demonstrate the function in a program that sks the user how many times the coin should be tossed and the coin then simulates the tossing of the coin that number of times.arrow_forward

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 it. This function should be called by main once for each of the five scores to be entered. 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 of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100.arrow_forward
