使用getch()来保持命令提示符打开Visual C ++ 2010 [英] using getch() to hold command prompt open Visual C++ 2010
问题描述
我目前正在学习c ++从一本名为Ivor Hortons开始Visual c + + 2010。
Im currently learning c++ from a book called 'Ivor Hortons Beginning Visual c++ 2010'.
在我到目前为止所有的例子,使用getch()保持打开命令提示符,有时从main方法结束时删除return 0语句。
In all the examples i've attempted so far I've had to use getch() to hold open the command prompt, and sometimes remove the return 0 statement from the end of the main method.
这是一个变化的windows 7它会进一步下线吗?这是没有问题,这一刻,但因为这不包括在书中,我想知道是否可能是我设置了错误。
Is this a vagary of windows 7 and will it cause problems further down the line? It's no problem doing this at the moment but since this is not included in the book I was wondering if it might be something I've set up wrong.
非常感谢: )
推荐答案
getch()
不是操作系统特定的,不是直接便携。在 C ++
中执行此操作的首选方法是使用 std :: cin.get();
。
getch()
is not operating system specific, but it is not directly portable. The preferred method for doing this in C++
is to use std::cin.get();
.
main
函数可以返回0
需要实际具有该代码,见下文)。
The main
function can return 0
implicitly (you don't need to actually have that code, see below).
int main()
{
// valid, return 0 implied.
}
See this question for more details about the implicit return 0
from main
.
