const map<int,int> A:: myMap = A::create_map(); int main() { } 假设是vector。能够使用 #include <iostream> #include <vector> using namespace std; class A { public: static vector<int> v2; void show() { for(vector<int>::iterator i = v2.begin() ; i!= v2.end(); i++) ...
count: The number of elements to be assigned the value. value: The value to be assigned. Here is an example: Using fill_n C++ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 #include <algorithm> #include <vector> #include <iostream> int main() { std::vector<int> vec(10); std::fill...
Method 1is probably the easiest to understand. Just copy each element from the array and push it into the back of the vector. Alas, it's slow. Because there's a loop (implied with the copy function), each element must be treated individually; no performance improvements can be made based...
I am migrating the code from matlab to c++ I have a auto generated c++ code from matlab here myfun(coder::array<double, 1U>& x) { //body here which is auto generated } Now I want to integrate this code with software But I have the respective input values in std::vector my_vec ...
