STANDARD TEMPLATE LIBRARY

AIM:
         To implement a C++ program to illustrate the concept of standard template library.

ALGORITHM:

Step 1: Include the header files

Step 2: Create a vector to store int

Step 3: Display the original size to store int

Step 4: Push 5 values into the vector using for loop

Step 5: Display extended size of vec

Step 6: Access 5 values from the vector

Step 7: Use iterator to access the values

PROGRAM:

#include <iostream.h>

#include <vector>

using namespace std;

int main()

{

  vector<int> vec;

  int i;

  cout << "vector size = " << vec.size() << endl;

  for(i = 0; i < 5; i++)

{

     vec.push_back(i);

}

  cout << "extended vector size = " << vec.size() << endl;

     for(i = 0; i < 5; i++)

{

     cout << "value of vec [" << i << "] = " << vec[i] << endl;

  }

  vector<int>::iterator v = vec.begin();

  while( v != vec.end()) {

     cout << "value of v = " << *v << endl;

     v++;

  }

  return 0;

}

SAMPLE OUTPUT:

vector size = 0

extended vector size = 5

value of vec [0] = 0

value of vec [1] = 1

value of vec [2] = 2

value of vec [3] = 3

value of vec [4] = 4

value of v = 0

value of v = 1

value of v = 2

value of v = 3

value of v = 4

RESULT:

                Thus a C++ program to illustrate the concept of standard template library is implemented successfully.
