cout string order

[viewsonic]

Hello,

(A) I am new and stuck on being able to cout strings that are found from "getline" & "find". I can cout the same order from the input file, but I can't manipulate that order. Notice that the input data is not in identical order except for the "Band".

(B) When I uncomment the two sections I commented out AND comment out the "cout"'s in the four "if" statements, why doesn't A,B,C,D print?

input.txt

=============
Band=U2
Genre=Rock
Albums=12
Members=Four
=============
Band=Metallica
Genre=Hard Rock
Members=Four
Albums=9
=============
Band=Skrillex
Members=One
Albums=7
Genre=Electronica
=============

main

#include<iostream>
#include<fstream>
#include<string>
using namespace std;

int main()
{
	ifstream file("input.txt");
	if (!file.is_open()) 
	{
	        cerr << "Failed to open file." << endl;
	        return (EXIT_FAILURE);
	}
//	string Atemp,Btemp,Ctemp,Dtemp,A,B,C,D;
	for (string line;(getline(file,line));)
	{
		if ((line.find("Band") != string::npos))
		{
			const size_t start_pos = line.find("Band");
			string Atemp = line.substr(start_pos+5);
			const size_t stop_pos = Atemp.find("\n");
			string A = Atemp.substr(0, stop_pos);	
			cout << endl << A << "-";		
		}
		if ((line.find("Genre") != string::npos))
		{
			const size_t start_pos = line.find("Genre");
			string Btemp = line.substr(start_pos+6);
			const size_t stop_pos = Btemp.find("\n");
			string B = Btemp.substr(0, stop_pos);
			cout << B << "-";
		}	
		if ((line.find("Albums") != string::npos))
		{
			const size_t start_pos = line.find("Albums");
			string Ctemp = line.substr(start_pos+7);
			const size_t stop_pos = Ctemp.find("\n");
			string C = Ctemp.substr(0, stop_pos);
			cout << C << "-";
		}
		if	((line.find("Members") != string::npos))
		{
			const size_t start_pos = line.find("Members");
			string Dtemp = line.substr(start_pos+8);
			const size_t stop_pos = Dtemp.find("\n");
			string D = Dtemp.substr(0, stop_pos);
			cout << D << ";";
		}	
//		cout << A << "-" << B << "-" << C << "-" << D << ";";
  	}
	cout << endl;
	system("PAUSE");   
	return 0;
}

cout

U2-Rock-12-Four;
Metallica-Hard Rock-Four;9-
Skrillex-One;7-Electronica-

Thanks in advance for any help.

(A)
you could consider adding the results in a vector.

  vector<string> v;
  while(getline(file, line));
     v.push_back(line);

after you've done that you can use the vector to manipulate your input.
You could for example create a for-loop like this:

    for(int i = 0; i < v.size(); i++)
       //add your loop here. 

since you can now select your seperate elements (v[8] works too for example), you can create a function to show it in any order you like.

(B)
This is because you are defining the strings again in the if-scope.
remove the words "string" in these positions and it will work.

you basically did this:

int i = 12;
    if (i > 3) {
        int i = 6;
        cout << i << endl;
    }
    cout << i << endl;

output:

6
12
