Consider the following function: int fives (int n) {if (n%5 == 0) return 0; else return 1;} a. What is returned to answer if main calls: int answer = fives(15); _____ b. What is returned to answer if main calls: int answer = fives(26); _____ c. What is returned to answer if main calls: int answer = fives(ceil(squareroot (62.5))); _____ Write a value-returning function to calculate the root of a quadratic equation: root = -b +/b^2 - 4ac/2a given a, b, c are the parameters. Show a sample call in main to this function. Write a void method to calculate the area (1/2bh) and hypotenuse/h2 + b2 of a right triangle, given the base and height in parameters, and return both answers to main by reference. Show a sample call in main to this function
