c++ vector size 0 code example
Example 1: c++ vector size
#include <vector>
int main() {
std::vector<int> myVector = { 666, 1337, 420 };
size_t size = myVector.size();
myVector.push_back(399);
size = myVector.size();
}
Example 2: 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;
}
