vscode 用户代码片段

如何新建代码片段

左下角(齿轮)设置 --> 用户代码片段 --> 输入名字新建代码片段

我的在右下角

输入名字新建即可

下面附上我的代码片段

代码片段格式

生成代码片段

输入完代码后记得 Ctrl + Z 结束运行，片段会生成到同目录下的 1.txt 中,直接复制即可

#include <bits/stdc++.h>
using namespace std;

int main() {
  freopen("1.txt", "w", stdout);
  string s;
  while(getline(cin, s)) {
    cout << "\"" << s << "\",\n";
  }
  return 0;
}
