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