In this article, we’ll tackle the Capitalize program, its requirements, and how to test it.

Description

This simple program picks a string and return the first letter of it in uppercase.

For this sample program, each solution should return the string with the first letter in uppercase. In other words, do not change anything else about the input string.

In addition, there should be some error handling for situations where the user doesn’t input a string.
