无法看到C程序输出 [英] Unable to see the C program output

问题描述

我输入了一个使用dos框和Turbo C编译器在C中计算SI的程序。

我的程序 被编译但是没有显示输出。< br $> b $ b

我尝试过：



我还输入了一个程序显示'你好世界'。它完美地显示了输出。但是当我尝试执行SI程序时，输出会在闪烁时打开和关闭，而不显示输出。

I have typed a program to calculate SI in C using dos box and Turbo C compiler.
My program gets compiled but it doesn't show the output.

What I have tried:

I have also typed a program to show 'hello world'. it shows the output perfectly. but when i try to execute the SI program , the output opens and closes in a blink, without showing the output.

推荐答案

问题是当你运行控制台时应用程序，它期望来自用户的输入 - 如果它没有得到它，它不会等待 - 它关闭，控制台窗口也关闭。结果，你在屏幕上看不到任何东西，因为它不存在足够长的时间。

所有你要做的就是强制它在关闭之前等待你： br />

The problem is that when you run a console app, it expects input from the user - and if it doesn't get it, it doesn't wait around - it closes and the console window is closed as well. As a result, you can't see anything on the screen because it just isn't there for long enough.
All you have to do is "force" it to wait for you before closing:

void main()
   {
   printf("Hello World!\n");
   getchar();
   }
