I've been having difficulties in searching a text in a text file when I choose case 4 or 'show video details'. It seems that ifstream
in a switch statement is not working. This is my code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
int choice;
//4
string line;
bool iffound = false;
string id1;
ifstream file("test.txt");
menu:
cout << "MENU" << endl
<< endl;
cout << "[1] NEW VIDEO" << endl;
cout << "[2] RENT A VIDEO" << endl;
cout << "[3] RETURN A VIDEO" << endl;
cout << "[4] SHOW VIDEO DETAILS" << endl;
cout << "[5] DISPLAY ALL VIDEOS" << endl;
cout << "[6] CHECK VIDEO AVAILABILITY" << endl;
cout << "[7] CUSTOMER'S MAINTENANCE" << endl;
cout << "[8] EXIT PROGRAM" << endl;
cout << "Choice: ";
cin >> choice;
switch (choice)
{
case 1:
break;
case 2:
break;
case 3:
break;
case 4:
{
file.open("test.txt");
cout << "<< SHOW VIDEO DETAILS >>" << endl
<< endl;
cout << "Enter Movie ID: ";
cin >> id1;
string idnum1 = "VIDEO ID: " + id1;
cout << idnum1 << endl;
while (file.good())
{
getline(file, line);
if (line == idnum1)
{
iffound = true;
for (int i = 0; i <= 3; i++)
{
getline(file, line);
cout << line << endl;
}
break;
}
}
file.close();
if (iffound != true)
{
cout << "Video not found!" << endl;
}
}
break;
case 5:
break;
case 6:
break;
case 7:
break;
case 8:
break;
}
}
And this is my text file:
VIDEO ID : 1
MOVIE TITLE : IT
GENRE : HORROR
PRODUCTION : NEW LINE CINEMA
NUMBER OF COPIES: 0
it.jpg
VIDEO ID : 2
MOVIE TITLE : THE CALL
GENRE : HORROR
PRODUCTION : YONG FILM
NUMBER OF COPIES: 3
thecall.jpg
VIDEO ID : 3
MOVIE TITLE : I AM LEGEND
GENRE : HORROR
PRODUCTION : VILLAGE ROADSHOW
NUMBER OF COPIES: 6

When I input a valid Id
, for instance, 1
, it outputs 'video not found', when clearly the Id is present.
But when I try this code, where there is no switch
statement, it works:
int main()
{
ifstream file("test.txt");
string line;
bool find = false;
string id;
string img;
cout << "Enter movie ID: ";
cin >> id;
string idnum = "VIDEO ID : " + id;
cout << idnum << endl;
while (file.good())
{
getline(file, line);
if (line == idnum)
{
find = true;
for (int i = 0; i < 4; i++)
{
getline(file, line);
cout << line << endl;
}
getline(file, img);
cout << img;
}
}
file.close();
if (find != true)
{
cout << "Movie Not Found" << endl;
}
return 0;
}
But I need to run it in a switch statement.
