Strings!

Adrioth (4)
Hey, I'm trying to write a program which does the following:

Takes a string, displays it in all capitals
displays it in all lower case letters
Counts the amount of spaces
Counts the amount of words


I've been playing with this for awhile now, and I have a few error c2109; subscript requires array or pointer errors..I'm not sure what to do! Erros are in lines 68,75,85,94,98(twice)

return(0);

}



here's my code so far, any help would be great! :P

Made some progress, everything works now...however I'm having trouble getting the 'number of words' to actually print....silly problem but just can't seem to do it

I'm getting errors, or a very large number. I know it's probably something simple...just can't quite grasp the issue yet

}


int wordcount(char string[])

{

}



my current print statement is on line 55, if I have it anywhere else, nothing comes up at all...yet in line 55 I seem to get errors
