c++ vector lengtb code example
Example 1: 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
}
Example 2: vector length c++
#include <vector>
int main () {
std::vector<int> v;
auto size = v.size();
}
