如何开始使用 IDE，尤其是 Qt Creator? [英] How to get started with IDEs, Especially Qt Creator?

问题描述

我是一名高中生，只用 Turbo C++ 编写过代码.我不知道 IDE 是如何工作的，我安装了 Qt Creator 来开始学习 GUI 编程，但我什至无法让它运行简单的 C++ 代码.我不知道要包含哪些文件.注意:我是个新手.我在 YT 上找到的教程令人困惑且不清楚.我不知道为什么会这样.这是我的代码:

I'm a highschool student, who have only ever coded in Turbo C++. I have no idea how IDEs work, I installed Qt Creator to start learning GUI programming but I can't even get it to run a simple C++ code. I doesn't know what files to include. NOTE: I'm a total newbie. The tutorials I found on YT are confusing and not clear. I have no idea why this is happening. This is my code:

#include<IOSTREAM.H>
#include<CONIO.H>

void main() {
    clrscr();
    cout << "Hello World!";
    getch();
}

我确实构建了所有，然后运行，但我遇到了这个问题:

I did build all, then run but I got this Issue:

没有将目标设为all"的规则.停止.

No rule to make target `all'. Stop.

推荐答案

1. clrscr() 是特定于 Windows 的(或者是特定于 Turbo C++ - 我忘记了)，无论如何；不要使用它.

1. clrscr() is Windows specific (or is it Turbo C++ specific - I forget), in any case; don't use it.

cout 应该是 std::cout.

你应该包括iostream"而不是那些过时的.h"版本(此外，标题名称是小写的，而不是大写的).

you should include "iostream" not those obsolete ".h" versions (besides, the header names are lowercase, not uppercase).

void main 无效.main always 返回 int.

注意:这些错误与 Qt 或 qtcreator 无关.它们只是您代码中的简单明了的错误.阅读 Qt 文档并尝试一些教程.

Note: these bugs have nothing to do with Qt nor qtcreator. They are just, plain and simple, bugs in your code. Read Qt documentation and try out some tutorials.
