我尝试调试vs代码中的一些代码。一切正常,但是当我尝试在控制台中输入内容时,什么也没发生。
我的代码:
#include <stdio.h>
#define SIZE 20
int main()
{
char arr[SIZE];
fgets(arr, SIZE, stdin);
puts(arr);
return 0;
}
如您所见,我使用fgets()
从控制台读取字符串,但是当调试达到该功能时,所有内容都会停止,并且我无法输入任何内容。
只有黑色的窗户。
但是,当我使用gets()
时,例如以下示例:
#include <stdio.h>
#define SIZE 20
int main()
{
char arr[SIZE];
gets(arr);
puts(arr);
return 0;
}
一切正常。
问题出在哪里?也许调试控制台无法读取任何内容?如何使用fgets()
输入任何内容?
这是我的launch.json:
