Thread: counting characters and vowels and constants including after spaces.

i am trying to write a program that counts characters, vowels and constants in a string.
it works fine when entering one word i.e hello but when i add a space i.e hello Jon it doesn't count after the space
any ideas would be great help, prob something simple.

I'm sure it is. I will take a guess, and say you need to read the documentation for scanf carefully to identify and possibly correct your problem. If you don't find your answer there, post your code.

do you no the code to include spaces (white spaces) maybe i need to put that in my scanf

another option is to avoid scanf. use fgetc to read one character at a time so you can test each one individually.

You could use the "%[...]" format specifier, replacing the ... with the characters you want to allow (or ^ followed by the characters you don't want to allow, such as \n). Personally though, I would use fgets, since it makes it easy to protect against buffer overflows too.
