what is vector in c++ code example
Example 1: how to create a vector in c++
#include <vector>
using namespace std;
int main()
{
vector<int> vect;
vect.push_back(10);
for (int x : vect)
cout << x << " ";
return 0;
}
Example 2: vector in c++
vector<int> g1;
for (int i = 1; i <= 5; i++)
g1.push_back(i);
cout << "Output of begin and end: ";
for (auto i = g1.begin(); i != g1.end(); ++i)
cout << *i << " ";
cout << "\nOutput of cbegin and cend: ";
for (auto i = g1.cbegin(); i != g1.cend(); ++i)
cout << *i << " ";
cout << "\nOutput of rbegin and rend: ";
for (auto ir = g1.rbegin(); ir != g1.rend(); ++ir)
cout << *ir << " ";
Example 3: vectors in c++
vector <int> vc;
Example 4: vector keyword in c++
template < class T, class Alloc = allocator<T> > class vector;
