vector c++ size initialize code example
Example 1: how to create a vector in c++
#include <vector>
std::vector<type> name;
std::vector<double> lol = {66.666, -420.69};
Example 2: 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 3: how to initialize vector
vector<int> vect{ 10, 20, 30 };
Example 4: c++ create vector of size
std::vector<int> arr(20);
for(int x = 0; x < 20; ++x)
arr[x] = x;
