Ex3 (4 points) Write a program that has two functions: main() and findMinMax (). In main(), five numbers (16, 28, 37, -14, 22) are stored in these variables (t1, t2, t3, 14, 15), respectively, The main() calls findMin Max () to find the minimum and the maximum of these numbers and also computes the average value. The findinMax () should use reference parameters to return the results (minum, maxNum, average) back to the main () function. Finally, the main() prints the values of minNum, maxNum and average
