c++ vector insert at index code example
Example 1: inserting at start in vector c++
vector_name.insert(vector_name.begin(), element_to_be_inserted);
vector_name.insert(vector_name.begin()+(x-1), element_to_be_inserted);
vector_name.push_back(element_to_be_inserted);
Example 2: insert at position in vector c++
v.insert(v.begin() + i, v2[i])
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;
}
