c++ push vector into vector code example
Example 1: how to append one vector to another c++
vector<int> a;
vector<int> b;
a.insert(a.end(), b.begin(), b.end());
Example 2: Appending a vector to a vector in C++
Input:
vector<int> v1{ 10, 20, 30, 40, 50 };
vector<int> v2{ 100, 200, 300, 400 };
v1.insert(v1.end(), v2.begin(), v2.end());
Output:
v1: 10 20 30 40 50 100 200 300 400
v2: 100 200 300 400
Example 3: add to vector c++
#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;
}
