printf的不打印在控制台上 [英] printf not printing on console

问题描述

我入门C语言。我使用的Eclipse（JUNO）作为我的IDE和安装CDT插件。我也将解压缩mingw64（GCC编译）。我写了一个非常简单的程序，看看它是否工作。这是我的code：

I’m getting started in the C language. I am using eclipse (juno) as my IDE and installed CDT plugin. I have also unpacked mingw64 (GCC Compiler). I wrote a very simple program to see if it works. This is my code:

#include <stdio.h>

int main()
{
    int age;
    printf("Hello, please enter your age:\n");
    scanf("%d", &age);
    printf("Your age is %d", age);
    return 0;
}

问题是，输出缓冲器填充有第一的printf 但不输出到控制台的字符串值。我必须输入一个数字，然后才缓冲区中的所有数据倒到控制台，所以我看到控制台是这样的：

The problem is that the output buffer is filled with the string value of the first printf but does not output it to the console. I have to enter a number, and only then the buffer pours all the data to the console so I see the console something like this:

1
Hello, please enter your age:
Your age is 1

代替期望是什么是：

instead of what is expected that is:

Hello, please enter your age:
1
Your age is 1

现在，我发现我可以使用 fflush（标准输出）后的第一个的printf 但我不认为这个解决方案是优雅的，甚至是必要。我如何能解决这个任何想法？

Now, I found that I can use fflush(stdout) after the first printf but I don't think that this solution is elegant and even necessary. Any ideas on how I can overcome this?

修改 - 因为我正在学习这在我的大学，我不能使用任何没有在课程中所学，所以我可以的仅使用的printf 和 scanf函数

EDIT - because I'm learning this in my university, I can't use anything that wasn't learned in the course so I can only use printf and scanf

新修改 - 我想我已经找到了这种解释。正如我所说的，我输出到Eclipse内部控制台视图。奇怪的是，如果我编译和从Windows的命令行运行程序，我得到的通缉的结果。因此，我认为，Eclipse是实际编写输出到文件和presenting它在控制台窗口。我怎么可以强制Eclipse在我的运行配置打开一个真正的命令行窗口？

NEW EDIT - I think I have found an explanation for this. As I said, I am outputting to the console view inside Eclipse. The strange thing is that if I compile and run the program from the command line of Windows, I get the wanted result. Therefore, I think that eclipse is actually writing the output to a file and presenting it in the console window. How can I force eclipse to open a real command line window in my run configurations?

推荐答案

确定 - 显然这是日食的一个已知的bug。此错误与WONT-FIX的决议决定。
不知道为什么，虽然。这里是链接：

的Eclipse。c控制台错误

OK - apparently this is a known bug of eclipse. This bug is resolved with the resolution of WONT-FIX. have no idea why though. here is the link:
