vector of vector stl initialization c++ code example
Example 1: initialize 3d vector c++
vector<vector<vector<double>>> f(3, vector<vector<double>>(4, vector<double>(5)));
Example 2: how to create a vector in c++
// CPP program to create an empty vector
// and push values one by one.
#include <vector>
using namespace std;
int main()
{
// Create an empty vector
vector<int> vect;
//add/push an integer to the end of the vector
vect.push_back(10);
//to traverse and print the vector from start to finish
for (int x : vect)
cout << x << " ";
return 0;
