C语言-------memcpy()函数的使用

#include 
#include 

int main()
{
	char buf1[]="hello";
	char buf2[]="world";
	char buf[20];
	
    int	buf1_len = strlen(buf1);
	int buf2_len = strlen(buf2);
	
	memcpy(buf,buf1,buf1_len);//从存储区buf2复制n个字节到存储区buf
	
	printf("buf = %c",buf);
	
    return 0;
}

运行结果：
buf = helloworld
