Question

use the following pieces of code and write the function printVector that will display the vector by using a function template, and using a const_iterator for outputting vector elements. (Consider using auto in your iterator's declaration)

// prototype for function template printVector

template <tyename T> void printVector(const vector <T>& integers2);

.....

vecctor <int> integers;

//function push_back is in vectors

integers.push_back(2);

integers.push_back(3);

integers.push_back(4);

cout << " Output vector using iterator notation: ";

printVector(integers);

// Your code here......

Explanation / Answer

#include<iostream>

#include<vector>

using namespace std;

template <typename T>

void printVector(const vector <T>& integers2);

int main()

{

vector <int> integers;

//function push_back is in vectors

integers.push_back(2);

integers.push_back(3);

integers.push_back(4);

cout << " Output vector using iterator notation: ";

printVector(integers);

}

template <typename T>

void printVector(const vector <T>& integers2)

{

for (vector<int>::const_iterator iter = integers2.begin(); iter != integers2.end(); ++iter)

{

cout << *iter << " ";

}

cout << endl;

}

/*output:

Output vector using iterator notation: 2 3 4

*/
