size vector c++ 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: vector length c++
#include <vector>
int main () {
std::vector<int> v;
auto size = v.size();
}
Example 3: finding the size of vector in c++
vector<int> a;
cout <<" " << a.size();
Example 4: find vector size in c++
vectorName.size();
Example 5: c++ create vector of size
std::vector<int> arr(20);
for(int x = 0; x < 20; ++x)
arr[x] = x;
