int main()

std::vector<int> v(N, default_value);
// Use above vector to initialize the two-dimensional vector
std::vector<std::vector<int>> matrix(M, v);
return 0;
}c++ initialize a vector
#include <bits/stdc++.h>

// This vector initializes with the values: 10, 20, and 30
vector<int> vect{ 10, 20, 30 };

}initialize vector c++
// CPP program to create an empty vector
// and push values one by one.
#include <bits/stdc++.h>
using namespace std;
int main()
{
int n = 3;
// Create a vector of size n with
// all values as 10.
