Mac C printf variable making new line using fgets

[Cabbit]

	// Get username
	printf("What was your name again? ");
	
	// Get username using fgets, this is how to do it without a security error
    fgets(name, 15, stdin);
	// End get username
	
	// The user hears someone calling their name, using variable called name
	printf("Mysterious Voice %s %s \n", name, name);

My expected output is "Mysterious Voice name name", my actual output is "Mysterious Voice name
name

"

Anyone know why and how to fix it. name is a char

The newline is coming from the fgets. You can strip it after you read it, that should take care of it.

...more precisely, it's coming from the user input. fgets() gives you everything the user inputs up to and including the \n. like lee said, strip it, and you're golden.

i fixed it as you suggested using

// Remove \n from name
	len = strlen(name);
	if( name[len-1] == '\n' )
		name[len-1] = 0;

I was using gets() before which did not have the same problem.

Good move though

fgets() is safer than gets() because the former includes a buffer length.
