storing and comparing a string

Dark_Helmet · 03-10-2003, 06:57 PM

Essentially, yes. I handle strings a little differently than the way you have. Just how I learned them is all...

Code:

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

#define STRING_LENGTH 17  // max # of characters + 1
                          //   completely arbitrary
int main(void)
{
  int x;
  char s1[STRING_LENGTH]; // how I'm used to seeing it
  char s2[STRING_LENGTH]; // .. ditto ..

  strcpy ("password", s1);  // Copy the string into s1

  printf(" Enter a password:\n");
  scanf("%s", s2);

  x = strcmp(s1,s2);
  if (x == 0)
    printf("password accepted");
  else
    printf("access denied");
              
  return(0);
}

that seems to work so far, i'll continue writing the program and i'll see what other bumps come up!

thanks for your help! i REALLY REALLY appreciate it

in this line: char s1[] = "password", s2[];
you'll probably get an unknown array size for s2[]

and i assume you know you have to declare x as something (bool?)

take the terminator off the "if..." statement... but you knew that ;-)

i guess you can initialize s2[] to a known string value just for comparison

Man that is Genius, using the switch function to handle the four different directions apropriately!!. I would never have thought of it. well atleast i learned how to use the compare string function.

this is one of the best places to get suggestions!

thanks guys
