C++ || Snippet – How To Find The Minimum & Maximum Of 3 Numbers, Print In Ascending Order

April 29, 2012 admin No comments

This page will demonstrate how to find the minimum and maximum of 3 numbers. After the maximum and minimum numbers are obtained, the 3 numbers are displayed to the screen in ascending order.

This program uses multiple if-statements to determine equality, and uses 3 seperate int varables to store its data. This program is very basic, so it does not utilize an integer array, or any sorting methods.

NOTE: If you want to find the Minimum & Maximum of numbers contained in an integer array, click here.
