Question

LAB 13

Please use correct division of code into .h and .cpp files and Comments in code explain what's being done. Thanks you very much for your help

Create an STL vector of 10 integers and store initial values (0 to 9 is fine).
Use the std::random_shuffle algorithm to shuffle the list.
Print the list. (use an iterator in a regular for loop)
Use the std::sort algorithm to sort the list.
Print the list again. (use a range-based for loop)

Optional Challenge: use a predicate to remove the even numbers, then print the list. Which std algorithm should you use?

You will need to locate the documentation for random_shuffle, sort, and for each either in VS help or with Google. Once you leave this class, you will need to be able to find information like this on your own.

Checklist

1. Uncheck the Create directory for solution checkbox in the New Project Dialog
2. Project/solution named correctly
3. Correct comments at top
4. Consistent indentation (Use Edit/Advanced/Format Document)
5. Good variable names
6. Overall neat organization
7. Comments in code explain what's being done
8. Correct division of code into .h and .cpp files
9. Use of #pragma once in .h files (or, #ifndef)
10. #include "stdafx.h" in cpp files (or, suppress pch)

Answer 1

#include <bits/stdc++.h>
// #include <stdafx.h>
//uncomment the above header when running in visual studio
#ifndef vsize
#define vsize 10
#endif
using namespace std;

int main()
{
   vector <int> v(vsize);// Declaring vector of size 10
   for (int i=0;i<v.size();i++){
       v[i] = i;
   }
   //using random shuffle
   random_shuffle(v.begin(),v.end());

   vector <int> :: iterator it; //Declaring iterator
   cout<<"Printing using iterator\n";
   for(it = v.begin();it!=v.end();it++){
       cout<<*it<<endl;
   }

   sort(v.begin(),v.end()); // Using sort function
   cout<<"After sorting ,printing using index\n";
   for(int i=0;i<v.size();i++){
       cout<<v[i]<<endl;
   }
}

Note: If any doubts then please comment. Hope it helps
