C++

Write the declarations for an array of structs that can be used to store all the top 10 hits for every week of the year. The data for the first six weeks of 2012 is stored in a text file (TopHits.txt) that is supplied to you. Each line in the file contains the song title followed by a | followed by the artist. The first 10 records are the hits for the first week (from 1 to 10), the next 10 records are the hits for the next week and so on. Write functions to:

1. Load the array of structs with data from the file.

2. Display the top hit for every week of the year.

You will be supplied with an input file, TopHits.txt (copy this list and save in doc as TopHits.txt)

For this program what are the....

(Repeat this section for each of your functions). Provide the function prototype here.

Explanation / Answer

#include<iostream>

#include<string>

#include<fstream>

using namespace std;

struct SongRecord

{

string title;

string artist;

};

int readFile(SongRecord array[])

{

ifstream in("TopHits.txt");

if(!in)

{

cout<<"input file doesnot exits"<<endl;

return 0;

}

int i=0;

string line;

while(!in.eof())

{

getline(in,line);

array[i].title=line.substr(0,line.find_first_of('|')-0);

array[i].artist=line.substr(line.find_first_of('|')+1);

i++;

}

return i-1;

}

void printRecord(SongRecord array[],int i)

{

int j=0;

int week=1;

int hit=1;

while(j<=i)

{

if(j%10==0)

{

cout<<"----------------Week :"<<week++<<"-----------------"<<endl<<endl;

hit=1;

}

cout<<"-------------Hit: "<<hit++<<"------------------"<<endl;

cout<<"title: "<<array[j].title<<endl;

cout<<"artist: "<<array[j].artist<<endl;

cout<<endl;

j++;

}

int main()

{

SongRecord array[1000];

int i=readFile(array);

if(i>0)

printRecord(array,i);

system("pause");

return 0;

}
