    sscanf

    I am trying to read in a user defined string. The user will enter two floats, and a name. The three items are separated by a single space. I'm trying to break up the three by sscanf and save the two numbers as separate floats and the name as a string. I know this doesn't work, Is the only way to use the single spaces to my advantage and break (the user defined entered things) the string up and read the parts I want and assign them separately!

    thanks for looking......cheers


    Code:
     printf("\nPlease type in two float values and one of the first names,\n");
    
    printf("followed by  all of which are separated by a single space:\n");
    
    sscanf("%f","%f","%s",float &num1, float &num2, char *p_user);

    Code:
    #include <stdio.h>
    
    int main ( void )
    {
      float a, b;
      char s[BUFSIZ];
    
      fgets ( s, sizeof s, stdin );
      sscanf ( s, "%f%f%s\n", &a, &b, s );
    
      printf ( "%f -- %f -- %s", a, b, s );
    
      return 0;
    }

    What, no return code checking... shame on you
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
