Question #294135

You can get the character (letter) at the nth index in a string by writing stringVar.charAt(n) or simply stringVar[n]. The returned value will be a string containing only one character (for example, "a"). The first character position is index 0, which causes the last one to be found at position stringVar.length - 1. In other words, an 8 character string has length 8, and its characters have positions 0 and 7. 1. Prompt the user for a string. 2. Write a function called three that will: take a string as a parameter return the 3rd character of the string 3. Display the original string and the result of the function, seperated by a colon (:), to the console. 4.

Modify the function so that if the third character is a space it will return the word "space". Sample Output User enters "Canada", output: Canada: n; User enters "Of course
