我有这样一个srt字幕文件
1
00:00:03,575 --> 00:00:05,134
Paul's letter to the Romans
2
00:00:05,134 --> 00:00:07,164
it's one of the longest and most significant things
3
00:00:07,165 --> 00:00:10,714
ever written by the man who was formerly known as Saul of Tarsus.

00:00:11,262 --> 00
据我所知,以下代码不编译,因为移动构造函数A被删除,因为互斥不可动。
class A {
public:
A(int i) {}
private:
std::mutex m;
};
int main() {
std::vector<A> v;
v.emplace_back(2);
}
但是,如果我想将我的A存储在一个std容器中,我应该怎么做呢?我很好,A正在“内部”的容器。
我正在尝试用这个要求构建正则表达式。
要求:
最大长度-5(如果是小数点,则为小数点)
十进制进动-最大2位数(如果是小数数字)。
数字-不需要是十进制数(不是强制性的)
代码:
<script>
function myFunction() {
var regexp = /^(?!\.?$)\d{0,5}(\.\d{0,2})?$/;
var num = 12345.52; // i will test here indiffernt ways
var n = regexp.test(num)
