strings

Does anyone know the best way to take a string as char, like "hello world"
or whatever, and print it out, where there are no characters / letters are
repeated? The string thus being shorter somewhat, but keeping the whitespaces?

you can allocate a new array that has the same size of the original
string, and copy the characters from the original string to the array in
a loop. Before copying each character, make sure that it's not identical
to the previously copied character (if it is, skip it and proceed to the
next one).
