将项目从VS2008迁移到VS2015时,我遇到了以下错误.

该项目建立在VS2008中,但在VS2015中出现上述错误.我可以知道我错过了什么.
直到昨天,Github Actions 还在我的存储库中工作。我没有在 .github/workflows/dev.yml 文件或 DockerFile 中做任何更改。
但是,突然在最近的推送中,我的 Github Actions 因错误而失败

格式是:hour:minute:second:millisecond:microsecond:nanosecond.
在下面的代码中,我希望在数组1中的所有10元素中初始化x.但是,它似乎没有起作用.我可以知道我在这里缺少什么吗?
int main() {
int *x = new int[10];
for(int i =0; i <10; ++i){
*x = 1;
x++;
}
for(int i = 0; i < 10; ++i)
