#vector in C++

code :

#include<iostream>

#include<vector>  // vector header file

#include<algorithm> // This header file contain sort method

using namespace std;

int main()

{

vector <int> v; // Declaration of vector int

v.push_back(10);

v.push_back(30);

v.push_back(20);   // To insert element into vector

v.push_back(90);

v.push_back(50);

int size = v.size(); // To get size of Vector

cout<<"Size of Vector : "<<size<<endl;

// sort the element of vector

sort(v.begin(),v.end()); // TO sort we have to pass two parameter 

                         //which are first element and second element

                         

v.pop_back();  // To Delete Elements from Array

v.pop_back();

size = v.size(); // To get size of Vector

cout<<"Size of Vector : "<<size<<endl;

for(int i=0;i<size;i++) // To display elements of vector

{

cout<<"vector "<<i+1<<" : "<<v[i]<<endl;

}
