数据结构示例之连接字符串

 以下为“连接字符串”的简单示例

1. 用c语言实现的版本

#include 
#include 

#define MAXLENGTH 128

/* //连接字符串 
void catstr(char *dest, char *sour)
{
	int destLength = strlen(dest);
	int srcLength = strlen(sour);
	int i = 0, j = 0;

	for (i = destLength, j = 0; j < srcLength; ++i, ++j)
	{
		dest[i] = sour[j];
	}

	dest[i] = '\0';
}
*/
//另一种实现方法
void catstr(char *des,char *sour)
{
	while(*des !=  '\0')
	{
		++des;
	}

	while((*des++ = *sour++) != '\0')
	{
		;
	}
}

void main()
{
	char dest[MAXLENGTH] = "Sit down";
	char sour[MAXLENGTH] = " please!";

	printf("原始字符串：%s\n", dest);
	printf("要追加的字符串：%s\n", sour);

	/* 连接字符串 */
	catstr(dest, sour);
		
	printf("操作结果：%s\n", dest);
}

运行结果如下图：
