i can't find the answer. please help

(a) A function named sum_avg() that takes in three floating-point numbers and sends back their sum and average via arguments by reference.
(b) A function named sum_avg() that takes in three floating-point numbers and sends back their sum with the return statement and their average via argument by reference. -
warm up about function swap()
#include<stdio. h>
void swap(int &, int &);
void main(){
int num1, num2;
printf("Enter 2 numbers > ");
scanf("%d%d", &num1, &num2);
if(num1 > num2)
swap(&num1, &num2);
printf("In ascending order: %d %d \n", num1, *num2);
}
void swap(int *a, int b)
{
int...
