Linux下的C语言编程——合并两个字符集合



合并两个字符集合为一个新集合,每个字符串在新集合中仅出现一次,函数返回新集合中字符串。

    如：

      s1集合{“while”,”for”,”switch”,”if”,”continue”}

      s2集合{“for”,”case”,”do”,”else”,”char”,”switch”}

      运行结果:

      while   for   switch   if  break   continue   case  do  else  char

#include <stdio.h>
#include <math.h>

void string_cmp(char (*str)[10],char (*str1)[10],char (*str2)[10],int n,int m)
{
	int i;
	int j;
	int len;

	char (*p)[m];//瀹氫箟涓€涓寚閽堟暟缁?
	p = str2;

	for(i = 0,len = 0; i < n; i++,len++)//灏嗘暟缁剆tr1鎷峰埌str涓?	{
		strcpy(str[i],str1[i]);
	}

	for(i = 0; i < m; i++)//鍒ゆ柇str1鍜宻tr2涓槸鍚︽湁鐩稿悓鍏冪礌
	{
		for(j = 0; j < n; j++)
		{
			if(strcmp(str2[i],str1[j]) == 0)
			{
				strcpy(str2[i],"ok");//鐩稿悓鐨勫厓绱犵敤ok浠ｆ浛
			}
		}


	}
	for(i = 0; i < m; i++)//灏唖tr2涓簬str1涓笉鐩稿悓鐨勫厓绱犲鍒跺埌str涓?	{

	}
	for(i = 0; i < len; i++ )//鎵撳嵃str
	{
		printf("%s\n",str[i]);
	}
}
