c++ initialize vector to 0 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++

// First include the vector library:
#include <vector>

// The syntax to create a vector looks like this:
std::vector<type> name;

// We can create & initialize "lol" vector with specific values:
std::vector<double> lol = {66.666, -420.69};

// it would look like this: 66.666 | -420.69

Example 3: how to initialize vector in c++ with all elements 0

vector<int> arr(10,0);

Example 4: initialize all elements of vector to 0 c++

vector<int> vect1(10); //number of elements in vector
    int value = 0;
    fill(vect1.begin(), vect1.end(), value);

Example 5: c++ initialize a vector

#include <bits/stdc++.h> 
#include <vector> 
using namespace std; 
  
int main() 
{ 
// This vector initializes with the values: 10, 20, and 30
  vector<int> vect{ 10, 20, 30 }; 

    return 0; 
}

Example 6: how to initialize vector

vector<int> vect{ 10, 20, 30 };
