Hello World C++ error语言 - cmath
Hello World C++ error - cmath
我是一个完全的c++初学者。我使用microsoft visual studio 2015与fltk 1.3。我遵循Bjarne Stroustrup的"使用c++的编程原则和实践"。我现在正在做的程序是Hello World，第52-54页的演练。
我写的代码(/从书和std_lib_facilities.h [www.stroustrup.com/Programming/include-std_lib_facilities.doc]的支持文档中复制)是:
//My first hello world program
#include "../../../std_lib_facilities.h"
int main() //C++ programs start by executing the function main
{
cout << "Hello, World!/n"; //output "Hello, world!"
keep_window_open(); //wait for a character to be entered
return 0;
}
然后我点击Build -> Compile，这发生了…

我认为这与std_lib_facilities.h文件有关。本书推荐使用fltk 1.1。X和visual studio 2005也许这也是问题的一部分?
你能给的任何见解都是非常感谢的。
谢谢。
应该可以
#include <iostream>
int main()
{
std::cout << "Hello, World!" << std::endl; //endl = /n
system("pause") //system pause = wait till user entering a char
return 0;
}
我也是一个新手，但这里是我使用visual studio的方法:
// my first program in c++
#include <iostream>
using namespace std;
int main()
{
cout <<"Hello World! I am a c++ program.";
return 0;
}
基本上你只需要使用#include
