Calculate the average smallest and the largest number in Array | Array Exercise | Array Logic Building Exercise |

This is the logic building program on array exercise. The program reads a group of numbers from the user and places them in an array of type float. Once the numbers are stored in the array, the program calculate the average of the input numbers, find the smallest and the largest number from the group of input numbers and print the result for all calculations.

float minMax(float[] ,int );
