Class Problem

[Sentoo]

Hi there,

I am current stuck on these problems with my current code.
WARNING: My current code has 3 different files so it might get confusing.
What I'm confused with is how go about doing things so my code works similar to the output below.

I. Write statements that modify the Cat objects in myCats such that each Cat
object has a random birth year between 2010 and 2016 and a random name from the
following array:

const int NUM_BREEDS = 10;
string catBreeds[NUM_BREEDS] = {“Abyssinian”, “American
Shorthair”, “Birman”, “Burmese”, “Exotic Shorthair”, “Main
Coon”, “Oriental”, “Sphynx”, “Persian”, “Siamese”};

Hint: use the rand() function to generate random numbers. Also, make sure that a new set of
random values is generated every time you run the program.

J. Write statements that print the Cat objects in myCats. Display your results in a
tabular format as shown in the sample screenshots below.

Hint: use the function setw( ) to display your results in a tabular format

Output should look something like this:
Cat Breed Year
-------------------------
1 Oriental 2012
2 Sphynx 2012
3 Exotic Shorthair 2015
4 Birman 2016
5 Oriental 2013

I suggest that you make setw() to a freestanding function.

...
void setw( Cat & cat)
{
    std::cout << cat.getYear() << '\t' << cat.getName() << '\n';
}

int main()
{
    ...
    std::srand(std::time(nullptr));  // sets a start seed by actual time
    std::vector<Cat> v_cats;;
    for( int i = 0; i < 100; ++ i)
    {
        v_cats.push_back( Cat( catBreeds[ std::rand() % NUM_BREEDS], std::rand() % 5 + 2011) );
    }
    for( Cat & cat : v_cats) setw( cat );
}

Are you aware of std::setw()?

Are you aware of std::setw()?

I wasn't :-(

[nuderobmonkey]

...
#include<vector>
#include<cstdlib>
#include<ctime> 
...
void print_cats( std::vector<Cat> & cats )
{
    for ( auto & cat : cats)
    {
        std::cout << std::setw(18) << cat.getName() << cat.getYear() << '\n';
    }
}

int main()
{
    ...
    std::srand(std::time(nullptr));  // sets a start seed by actual time
    std::vector<Cat> v_cats;
    for( int i = 0; i < 100; ++ i)
    {
        v_cats.push_back( Cat( catBreeds[ std::rand() % NUM_BREEDS], std::rand() % 5 + 2011) );
    }
    print_cats( v_cats );
}

Here you need to provide a matching Cat constructor.
