Warning: comparison between pointer and integer, assignment make integer from pointer without a cast?

Question

I'm getting these warnings right now and I'm not sure why. I've put the warning message in the code next to the line it corresponds with.

void removeNewLine (char * userName, int charLenght)
{
int i=0; 

do {
    if (userName [i]=='/n') //comparison between pointer and integer
    {
        userName [i]='/0'; //assignment makes integer from pointer w/o cast
    }
i++;
} while (i<charLenght);

}

Answer 1

You have the wrong slash. You want '\\n' for newline and '\\0' for NULL character.
