#include <iostream>
#include <string>
using namespace std;

int main()
{
	//错误示例下一行前不能有空格
	char chstr[] = "abcabc\
				   abcabc";
	//错误示例'\'要紧挨着换行处的字符
	char chstr1[] = "abcabc	\
abcabc";
	//方法1
	char chstr2[] = "abcabc\
abcabc";
	//方法2
	char chstr3[] = "abcabc"
		"abcabc";
	printf("chstr[]: %s\n", chstr);
	printf("chstr1[]: %s\n", chstr1);
	printf("chstr2[]: %s\n", chstr2);
	printf("chstr3[]: %s\n", chstr3);

	string str = "abcabc\
abcabc";
	string str1 = "abcabc"
		"abcabc";
	cout << "str:" << str << endl;
	cout << "str1:" << str1 << endl;
	return 0;
