第二种方法:利用<string>中的getline函数,按行读取,这样每一行内的所有空格也可以顺利读取 #include<iostream> #include<fstream> #include<string> using namespace std; int main() { ifstream ifs; ifs.open("test.txt", ios::in); if (readFile.is
列子如下: #include <iostream>classTest {public:boolyes(); };boolTest::yes() { std::cout<<"yes"<<std::endl;//return false;};intmain() { Test*t =newTest;boolr = t->yes(); std::cout<<"yes->"<< r <<std::endl;return0; } 用g++编译得到警告但是通过了,并且执行得到正确预期(...
#include <string> #include <iostream> int main() { std::string str = "Hello, World!"; // 修改字符串内容 str[7] = 'C'; std::cout << str << std::endl; // 输出: Hello, C++! return 0; } 在这个例子中,我们使用std::string来存储和修改字符串。
