Accessing a row in a vector of vectors in C++

Question

I have created a matrix of integers using vector of vectors. I need to print a particular row of the matrix. Is there a way to do it?

for (int j = 0; j < 100; j++)
{
    for (size_t i = 0; i < numberOfDataBits; ++i)
    {
        inputDataBits[i] = distribution(generator) % 2;       //generates input data stream
        count++;

    }


    big.push_back(inputDataBits);
    for (const std::vector<int>& v : big)
    {
        for (int x : v) std::cout << x << ' ';
        std::cout << std::endl;
    }
