how to initialize a vector to 0 in c++ code example

Example 1: 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 2: 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; 
}
