Appending a vector to a vector in C++
Input:
vector<int> v1{ 10, 20, 30, 40, 50 };
vector<int> v2{ 100, 200, 300, 400 };
//appending elements of vector v2 to vector v1
v1.insert(v1.end(), v2.begin(), v2.end());
Output:
v1: 10 20 30 40 50 100 200 300 400
v2: 100 200 300 400
adding element in vector c++

add to vector c++
// vector::push_back
#include <iostream>
#include <vector>
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;

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]
Insert into vector C++
// inserting into a vector
#include <iostream>
#include <vector>
int main ()
{
std::vector<int> myvector (3,100);
std::vector<int>::iterator it;
it = myvector.begin();
it = myvector.insert ( it , 200 );
myvector.insert (it,2,300);
// "it" no longer valid, get a new one:
it = myvector.begin();
std::vector<int> anothervector (2,400);
myvector.insert (it+2,anothervector.begin(),anothervector.end());
int myarray [] = { 501,502,503 };
myvector.insert (myvector.begin(), myarray, myarray+3);
std::cout << "myvector contains:";
for (it=myvector.begin(); it<myvector.end(); it++)
std::cout << ' ' << *it;
std::cout << '\n';
return 0;
