C++ 中是否有内置的向量函数来反转向量?
Is there a built-in vector function in C++ to reverse a vector in place?
或者你只需要手动完成?
Or do you just have to do it manually?
algorithm
标题中有一个函数 std::reverse
用于此目的.
There's a function std::reverse
in the algorithm
header for this purpose.
#include <vector>
#include <algorithm>
int main() {
std::vector<int> a;
std::reverse(a.begin(), a.end());
return 0;
}
