c++ vector size
#include <vector>
int main() {
std::vector<int> myVector = { 666, 1337, 420 };
size_t size = myVector.size(); // 3
myVector.push_back(399); // Add 399 to the end of the vector
size = myVector.size(); // 4
}

how to use vectors c++
#include <iostream>
#include <vector>
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;
}
finding the size of vector in c++
vector<int> a;
//to directly find the size of the vector;
//use a.size(;
cout <<" " << a.size();
vectors c++ set the size
#include <iostream>
#include <vector>
using namespace std;
int main(void) {
vector<int> v;
cout << "Initial vector size = " << v.size() << endl;
v.resize(5, 10);
cout << "Vector size after resize = " << v.size() << endl;
cout << "Vector contains following elements" << endl;
for (int i = 0; i < v.size(); ++i)
cout << v[i] << endl;
return 0;
