[SOLVED] Cs2134 homework assignment 3b

Enter data from the file MTA_train_stop_data.txt. The data from this assignment is from
http://www.mta.info/developers/download.html. (Please note that we will only be using some of
the information in this file for this assignment.1
)In the batch phase you will read all the data from the file called MTA_train_stop_data.txt into a
container of type vector.Your program will define the class trainStopData. It has the following private member variables :
string stop_id; // id of train stop (1st token)
string stop_name; // name of station (4th token)
double stop_lat; // latitude of train stop location
double stop_lon; // longitude of train stop location
Your class should also have a constructor and the following public member functions:
string get_id( ) const
string get_stop_name( ) const
double get_latitude( ) const
double get_longitude( ) const
1The data is in a common format; please read https://developers.google.com/transit/gtfs/reference?csw=1 for
more information.Written Part:The C++ STL has many functions and functors. Here is your chance to try some of them. In a
program when you use an STL algorithm add #include, and when you use an STL
functor add #include.For many of these problems you will need to look up information online. Here are some sources:

Fill in the correct code where you see a ****
vector A {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
vector B {1, 2, 1, 2, 1, 2};
vector C{1, 2, 3, 1, 2, 3};
vector D(6);
vector E(10);1. Copy the first 6 items of vector A into vector D
copy(****, ****, ****);
// D now equals {1, 2, 3, 4, 5, 6}2. Count the number of ones in vector B
cout << count(****, ****, 1);
//prints out the number of times a one appears in B3. In C++, there is a way to construct a unary functor from a binary functor. To do this you
use an adapter, a function called bind1st or bind2nd. We use bind1st in this example to
convert the STL binary predicate functor not_equal_to into a unary predicate by setting its
first value to 1.Count the number of items that are not equal to one in B
cout << count_if(B.begin( ), ****, bind1st(not_equal_to( ), 1));
/*prints out the number of times a one doesn’t appear in B.*/4. Test to determine if the first 3 items of A are the same as C.
bool same;
same = equal(A.begin( ), ****, ****);
25. Find the first item in vector A which equals 5
vector::iterator vecItr;
vecItr = find(****, ****, 5);
// returns an iterator to 5 in vector A
if (vecItr != A.end( ))
cout << ****;
// prints out the value pointed to by vecItr6. Find the first item in C that is greater than 2
vecItr = find_if(****, ****, bind2nd(greater(), 2));
// returns an iterator to 3 in C
if (vecItr != C.end( ))
cout << ****;
// prints out the value pointed to by vecItr
