Thread: Simple question with scanf()

i should read the whole thing with fgets and then convert the string with sscanf (+check for succesfull conversion)

You'll have fewer headaches if you don't consider using scanf, ever. Reading the whole line with fgets and then breaking it up with sscanf is much nicer. :-)

Code:

#include <stdio.h>

int main(void)
{
  int num;
  char string[100];

  /* Assume :string:ws:char:ws:number: */
  if (fgets(string, 100, stdin) == 0)
  {
    return 1;
  }
  else if (sscanf(string, "%*s %*c %d", &num) == 1)
  {
    printf("Num -- %d\n", num);
  }

  return 0;
}

But if you really have to do it the ugly way, it's not much different.

Code:

#include <stdio.h>

int main(void)
{
  int num;

  /* Assume :string:ws:char:ws:number: */
  if (scanf("%*s %*c %d", &num) == 1)
  {
    printf("Num -- %d\n", num);
  }

  return 0;
}
