according to the following code which can generate random binary numbers, how I can decrease these 2 for loop to one for loop?

C++
std::vector<int> b;
srand(time(0));

for (i = 1; i <= 4; i++)
{
    b.push_back(i);
}

for (i = 1; i <= b.size(); i++)
{
    b[i] = rand() % 2;
    std::cout << b[i] % 2 << " ";
}

Try this:

C++
std::vector<int> b;
srand(time(0));

for (int i = 0; i <= 4; i++)
{
   b.push_back(rand() % 2);
   std::cout << b[i] << " ";
}

excuse me, but you changed the range of i in for loop, in my code the range is from 1 to 4, but in your code its from 0 to 4 and when I change it to 1 to 4 normally its okay but in my project it never match with other parts and the result will be wrong
