initialization vector code example
Example 1: initialize vector of vector c++
#include <iostream>
#include <vector>
#define M 3
#define N 4
int main()
{
int default_value = 1;
std::vector<int> v(N, default_value);
std::vector<std::vector<int>> matrix(M, v);
return 0;
}
Example 2: c++ initialize a vector
#include <bits/stdc++.h>
#include <vector>
using namespace std;
int main()
{
vector<int> vect{ 10, 20, 30 };
return 0;
}
Example 3: how to initialize vector
vector<int> vect{ 10, 20, 30 };
Example 4: initialize vector c++
#include <bits/stdc++.h>
using namespace std;
int main()
{
int n = 3;
vector<int> vect(n, 10);
for (int x : vect)
cout << x << " ";
return 0;
}
Example 5: how to initialize a vector in c++
std::vector<type> name;
