Question

Write an algorithm for a program that reads in threenon-negative integer numbers and reports the maximum number,minimum number and average number. Write it in simple English, noneed of any programming language syntax.

Answer 1

Algorithm for finding maximum

Let the 3 numbers be x,y and z.

1. First find maximum between x and y using if statement.
2. if x is greater than y then compare x with z.If x is greater than z then x is maximum.Else z is maximum.
3. if x is smaller than y compare y with z.If y is greater than z then y is maximum else z is maximum.

Algorithm for finding minimum

1. First compare x with y.
2. If x is larger than y then compare y with z.If z is smaller then minimum is z else it is y.
3. If x is smaller then compare x with z.If z is smaller then z is minimum else it is x.

Algorithm for finding the average

1. Initialize a double variable to store the result and an integer to store the sum.
2. Assign the value sum/3 to the result and it is our average.
