我的程序从用户那里获取两个输入并找出它们是否是彼此的字谜到目前为止我得到了输入并按字母顺序对它们进行排序但不知道如何比较它们以打印出它们是否相同代码显然 string==strings 不正确

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

void sort_string(char*);

int main()
{
    char string[100];
    char strings[100];

printf("\nThis program will ask you for 2 words and compare them to see if they are anagrams of each other\n\n");


printf("Enter first word\n");
gets(string);

sort_string(string);

/*commented out for testing of function*/
/*printf("%s\n", string);*/

printf("Enter  second word for comparison\n");
gets(strings);
sort_string(strings);
/*commented out for testing of function*/
/*printf("%s\n", strings);*/


if (sizeof string==sizeof strings)
    printf("\nThe two words ARE  anagrams of each other.\n");
else
    printf("\nThe two words are NOT anagrams of each other.\n");


printf("\nThank You %d  %d\n\n",sizeof string, sizeoof strings);



   return 0;
}



/*function to sort in alphabetical order to be used for comparison*/ 
void sort_string(char *s)
{
   int c, d = 0, length;
   char *pointer, *result, ch;

   length = strlen(s);

   result = (char*)malloc(length+1);

   pointer = s;

   for ( ch = 'a' ; ch <= 'z' ; ch++ )
   {
      for ( c = 0 ; c < length ; c++ )
      {
         if ( *pointer == ch )
         {
            *(result+d) = *pointer;
            d++;
         }
         pointer++;
      }
      pointer = s;
   }
   *(result+d) = '\0';

   strcpy(s, result);
   free(result);
}

你需要使用strcmp().

qsort()此外，您可能需要考虑对sort_string().
