Thread: File I/O help please

I coded a program to open a file show content modify, clear or append some text to it.

Code:

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    char name[100];
    char content[100];
    char write[200];
    int sel;
    
    cout<< "Enter the name of the file to open: ";
    cin>> name;
    cin.ignore();
    ifstream a_file ( name );
    a_file.getline ( content, 100);
    cout<< "Contents of the file: "<< content;
    a_file.close();
    cout<< "\nSelect an action from below.\n1.)Modify  2.)Clear  3.)Add some more text: ";
    cin>> sel;
    
    if (sel == 1)
    {
            ofstream b_file ( name );
            cout<< "Enter something to write to the file: ";
            cin.getline (write, 200);
            b_file<< write;
            b_file.close();
            cin.ignore();
            cout<< "File modified successfully.";
            } else if (sel == 2)
            {
                   ofstream b_file (name, ios::trunc);
                   cout<<"File cleared Successfully.";
                   b_file.close();
                   } else if ( sel == 3 )
                   {
                          ofstream b_file (name, ios::app);
                          cout<< "Enter something to add to the file: ";
                          cin.getline ( write, 200 );
                          b_file<< write;
                          cin.ignore();
                          cout<< "Text added to the file seccessfully.";
                          b_file.close();
                          }else {
                                cout<< "Bad selection press 'Enter' to close";
                                }
    cin.get();
}

I'm stuck in if codes

Code:

 else if (sel == 2)
            {
                   ofstream b_file (name, ios::trunc);
                   cout<<"File cleared Successfully.";
                   b_file.close();
                   }

works fine but the other twos only open and clear file but don't write to file while they have to do so any help will be welcomed.

Ok I fixed it I had to put

Code:

cin.ignore();

after

Code:

 cin>> sel;

but thanx for the reply.
