C++入门 输出Hello World
#include <iostream>using namespace std;int main(){ cout << "Hello, world!" << endl; return 0;}
它等效于
#include <iostream>using namespace std;int main(){ cout << "Hello, world! \n"; return 0;}
#include <iostream>using namespace std;int main(){ cout << "Hello, world!" << endl; return 0;}
它等效于
#include <iostream>using namespace std;int main(){ cout << "Hello, world! \n"; return 0;}
首先让我们来看一个最简单的C++程序:#include <iostream> using namespace std; int main() { cout << ...
#include<iostream> using namespace std; int main() { cout << "The size of int is&nb...
#include<iostream> using namespace std; void addarr(int *k,int len); //文中形如sizeof(x)/sizeof(x[0]) 是用数组占用空...
