я учу с++ и мне гпт написал код а я не понимаю что он написал можете прокоментировать каждую строчку и что в ней написано
#include <iostream>
#include <vector>
#include <algorithm>
int main() {
srand(time(0));
std::vector<int> array1, array2, array3;
for (int i = 0; i < 3; ++i) {
array1.push_back(rand() % 4 + 1);
array2.push_back(rand() % 4 + 1);
array3.push_back(rand() % 4 + 1);
}
std::cout << "Array 1: ";
for (int num : array1) {
std::cout << num << " ";
}
std::cout << std::endl;
std::cout << "Array 2: ";

std::cout << num << " ";
}
std::cout << std::endl;

}
std::cout << std::endl;
