Compare two buffers: how to use memcmp


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

int main ()
{
  char str1[256];
  char str2[256];
  int n, len1, len2;

  printf ("Enter a sentence: "); 
  gets(str1);
  printf ("Enter another sentence: "); 
  gets(str2);

  len1=strlen(str1);
  len2=strlen(str2);

  n = memcmp ( str1, str2, len1 > len2 ? len1 : len2 );
  
  if (n>0) 
      printf ("'%s' is greater than '%s'", str1, str2);
  else if (n<0) 
      printf ("'%s' is less than '%s'",str1,str2);
  else 
      printf ("'%s' =  '%s'\n",str1,str2);
  return 0;
