how to append to vector c++ code example
Example 1: how to append one vector to another c++
vector<int> a;
vector<int> b;
// Appending the integers of b to the end of a
a.insert(a.end(), b.begin(), b.end());
Example 2: appending a vector in vector
a.insert(a.end(), b.begin(), b.end());
Example 3: add to vector c++
// vector::push_back
int main ()
{
std::vector<int> myvector;
int myint;
std::cout << "Please enter some integers (enter 0 to end):\n";
do {
std::cin >> myint;
myvector.push_back (myint);
} while (myint);
std::cout << "myvector stores " << int(myvector.size()) << " numbers.\n";
return 0;
}
Example 4: how to return a vector c++
std::vector<x>f();
Example 5: how to append to a vector c++
//vector.push_back is the function. For example, if we want to add
//3 to a vector, it is just vector.push_back(3)
vector <int> vi;
vi.push_back(1); //[1]
vi.push_back(2); //[1,2]
