问题

The code you provided is in C, and it seems like you're experiencing an issue where the program doesn't display anything after you delete everything following the "printf("Enter your name: ");" line. It's essential to retain the necessary parts of the code for it to work correctly.

Here's the corrected code:

#include <stdio.h>

int main()
{
   char name[20];

   printf("Enter your name: ");
   scanf("%s", name);

   printf("Hello %s ... Let's have fun !!! You=X | Computer=O\n", name);   
}

Ensure that you keep the #include <stdio.h> line at the beginning, and don't remove any of the quotation marks or semicolons. This code should work as expected in Visual Studio Code.

#include <stdio.h>

int main()
{
   char name[20];

   printf("Enter your name: ");
   scanf("%s", name);

   printf("Hello %s ... Let's have fun !!! You=X | Computer=O\n", name);   
}

"This code runs but does not display anything" 这段代码可以运行，但没有显示任何内容。

It doesn't display anything because of (line) buffering. 这是因为（行）缓冲的原因，所以没有显示任何内容。

Insert fflush(NULL); between printf and scanf, and it will start working as you expect. 在 printf 和 scanf 之间插入 fflush(NULL);，它将开始按照您的期望工作。
