Palindrome Program HELP!

[alex067]

I have a program where it will ask the user for a word and check if it's a palindrome.


The problem I have is:

1) I need to modify the program so that it will take sentences rather than a single word

2) The program does not terminate correctly, it will keep on asking for another word instead of executing with the final statement "The End"

3) I need to modify the program so that it will only take capital letters, removing anything that is not A through Z

Use std::getline.

2) The program does not terminate correctly, it will keep on asking for another word instead of executing with the final statement "The End"

Related to first. Stram extraction cannot give you an empty string, they will read at least one non-whitespace character.

3) I need to modify the program so that it will only take capital letters, removing anything that is not A through Z

It is better to modify inputted string replacing all letters with coresponding capitals.
