Using the Star structure defined in file p1 cpp write the fu

Using the Star structure defined in file p1 .cpp, write the function named findStars(). The function takes two input parameters: a vector of Stars and a string representing a star name or part of a star name. The function returns a vector of int representing the Draper numbers of the stars where the name was found. Use string:: find() to search the star names. Remember that string::find() return string::npos when the search parameter is not found. vector numbers; numbers = findStars(vStars, \"VEG\");

Solution

PROGRAM CODE:

//Modify the program ro suit your result.

#include <iostream>

#include <vector>

using namespace std;

//assuming this to be the structure for stars

struct Stars

{

   string name;

   int draperNum;

};

//function to find the star names in the vector

vector<int> findStars(vector<Stars> vStars, string part_star_name)

{

   vector<int> numbers;

   //iterating through the vector

   vector<Stars>::iterator itr = vStars.begin();

   while(itr != vStars.end())

   {

       Stars star = *(itr);

       string starname = star.name;

       //using find to look for the part of the string

       int found = starname.find(part_star_name);

       if(found != std::string::npos)

       {

           numbers.push_back(star.draperNum); // if found, then the corresponding draper number is pushed into the return vector

       }

       itr++;

   }

   return numbers;

}

int main()

{

   Stars star = {\"Sirius\", 134};

   Stars star2 = {\"vega\", 883};

   vector<Stars> vStars;

   vStars.push_back(star);

   vStars.push_back(star2);

   vector<int> numbers = findStars(vStars, \"veg\");

   //iterating to see the result

   vector<int>::iterator itr = numbers.begin();

   while(itr != numbers.end())

   {

       cout<<*itr;

       itr++;

   }

   return 0;

}

OUTPUT:

883
