Hi everyone,
So I am writing this program that is supposed to do the following:
Create a program that accepts a string from the user (not from the command line) and displays:
1. The string using upper-case letters, e.g. all lower-case letters are converted to upper-case letters
2. The string using lower-case letters, e.g. all upper-case letters are converted to lower-case letters
3. The string where the first letter of each word is upper-case and all other letters in the word are lower-case.
4. The string in "camel case", i.e. the first letter in the string is lower case, followed by alternating upper and lower case letters
I have done everything but number 4, the first letter in the string is lower case, followed by alternating upper and lower case letters.
I could really use some help. Any tips, hints, or help is much appreciated. Thank you.
