vector add elements cpp

vector<string> list;
list.insert(list.begin(), "Hello");

adding elements to a vector C++

#include<vector>
#include<algorithm>

// all the  std and main syntax ofcourse.

vector<int> pack = {1,2,3} ;

// To add at the END
pack.push_back(6);       // {1,2,3,6}

//  OR
// To add at BEGGINING 
pack.insert(pack.begin(),6) 	// {6,1,2,3,}		

adding element in vector c++

vector_name.push_back(element_to_be_added);

vector::insert

std::vector<int> vecOfNums{ 1, 4, 5, 11, -3, -10, 15 };

// Inserting a single element:
auto itPos = vecOfNums.begin() + 2; // Iterator to wanted postion
vecOfNums.insert(itPos, 77); // Insert new Element => 1, 4, 77, 5, ..
    
// Inserting part or full other vector
std::vector<int> otherVec{ 33, 33, 55 };
vecOfNums.insert(vecOfNums.begin() + 1, otherVec.begin(), otherVec.begin() + 2); // 1, 33, 33, 4, ..

C++ Vector Operation Add Element

#include <iostream>
#include <vector>
using namespace std;

int main() {
  vector<int> num {1, 2, 3, 4, 5};

  cout << "Initial Vector: ";

  for (const int& i : num) {
    cout << i << "  ";
  }

  num.push_back(6);
  num.push_back(7);

  cout << "
Updated Vector: ";

  for (const int& i : num) {
    cout << i << "  ";
  }

  return 0;
}

inserting element in vector in C++

vector_name.insert (position, val)

c++ insert vector into vector

//Insert vector b at the end of vector a
a.insert(std::end(a), std::begin(b), std::end(b));
