Our functions and declarations are all in the simdutf namespace. Thus you should prefix our functions and types with simdutf:: as required. If using C++20, all functions which take a pointer and a size (which is almost all of them) also have a span overload. Here is an example: std...

和原来一样,需要开辟一块新空间,然后释放掉原来的空间,再进行拷贝,此函数是为了节省空间。 代码语言:javascript 复制 #include<iostream>#include<vector>using namespace std;intmain(){vector<int>arr;arr.push_back(0);arr.push_back(0);arr.push_back(0);arr.reserve(10...
