how to add elements to vector in c++ code example
Example 1: adding element in vector c++
vector_name.push_back(element_to_be_added);
Example 2: 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 3: how to use vectors c++
using namespace std;
int main() {
//vector element size
const int size = 4;
//vector with int data type
//all elements are equal to 4
vector<int> myVect (size, 4);
for (int i=0; i<size; i++) {
cout << "Vector index(" << i <<") is: "<< myVect[i] << endl;
}
return 0;
}
