如何在 clion 调试下捕获控制台输出？

Question

我正在使用 clion 编写控制台应用程序。如果我只是运行程序，我可以看到 cout 调用的结果。但是，如果我对其进行调试，除了我的 exe 名称和 Process finished with exit code 0 之外，“调试控制台”选项卡下不会出现任何输出。是否有额外的步骤让控制台输出显示在 clion 的调试下？

或者这甚至不是特定于 clion 的，并且是使用 gdb 的人已经知道的一般事情？

GDB 操纵运行一个程序的进程。

GDB 会话示例：

% cat hello.c
#include<stdio.h>

main() {
    int count;

    for (count=0;count<10;count++)
       printf("Hello from CETS!\n");
}

% gcc -g hello.c
% gdb ./a.out

(gdb) p count
 = 0
(gdb) disp count
1: count = 0
(gdb) set count=8
(gdb) s
Hello from CETS!
6           for (count=0;count<10;count++)
1: count = 8
(gdb) 
7              printf("Hello from CETS!\n");
1: count = 9
(gdb) c
Continuing.
Hello from CETS!

Program exited with code 01.
(gdb) q
%

根据 JetBrains'post on clion debugger，您可以通过单击 "Debugger" 选项卡旁边的 "Console" 选项卡来查看调试输出：
