Thread: returning a string from a function

is anything wrong with this approach?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void str_output(char *x) 
{
	scanf("%s", x);
	
	/*
		do something with the string...
	*/
}

int main(int argc, char *argv[])
{
	char s[20];
  
	printf("Input string: ");
	str_output(s);
  

	/*
		do something with the string...
	*/

  return 0;
}

it seems to work but I keep looking around and waiting for something to hit me in the head

Of course, but apart from that, if the user ALWAYS enters less than 20 characters, is it ok?
