在形参s所指字符串数组中查找与形参t所指字符串相同的串，找到后返回该串在字符串数组中的位置（下标值），未找到则返回-1.ss所指字符串数组中共有N个内容不同的字符串，且串长小于M。

#include  <stdio.h>
    #include  <string.h>
    #define N 5
    #define M 8
    int fun(char (*ss)[M], char *t)
    {
       int i;
       for (i = 0; i < N; i++)
          if (strcmp(ss[i], t) == 0)
             return i;
       return -1;
    }
    int main()
    {
       char ch[N][M] = {"if", "while", "switch", "int", "for"}, t[M];
       int n, i;
       printf("The original string：\n");
       for (i = 0; i < N; i++)
          puts(ch[i]);
       printf("\n");
       printf("Enter a string for search:  ");
       gets(t);
       n = fun(ch, t);
       if (n == -1)
          printf("\nDon't found!\n");
       else
          printf("\nThe position is  %d .\n", n);
    }

程序结果：
