/* *	Introduction: *	测试C++中的字符串多行书写规则 */#include 
     
      #include 
      
       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;}输出结果：
