Which of the following function prototypes is valid for a function that calculate the mean (mean) of two integers such that the mean can be printed out from the main function? Example if f = 1, x2 = 2, then mean = 1.5 Select one or more: O a void mean (int f, int x2, float mean); Ob. void mean (int f, float &mean, int x2); Oc. float mean (int f, int x2); // function returns mean void mean (int f, int x2, float &mean); void mean (int f, int x2); /where mean is a global variable used in this function Of. int mean (int f, int x2); // function returns mean
