// Program Name:	2D Sum of Columns
// Chapter:			Chapter 5 - Arrays
// Description:		This program creates an array from 1 to 100 and displays it in a table.
//					Then prints the sum of 2 colums.

#define _CRT_SECURE_NO_WARNINGS // Disable warnings (and errors) when using non-secure versions of printf, scanf, strcpy, etc.
#include <stdio.h> // Needed for working with printf and scanf
