Write a function in C++ to read a text file "NOTES.TXT" , create another text file "NEW.TXT" to contain only the lines that start with letter 'A' .Display the contents of the file "NEW.TXT" .

void countA()
{
char ch;
notes b,c;   /*notes is a class previously defined in the program to
                    take  the contents of NOTES.TXT */
int count = 0;
fstream f;
f1.open("NOTES.TXT",ios::in|ios::binary);
f2.open("NOTES.TXT",ios::out|ios::binary);
if ( !f1 || !f2 )
{cout<<"FILE NOT OPENED!!!!!!!!!!";
exit(0);
}
f1.read( (char*)&b,sizeof(b) );
while ( !f1.eof() )
{
f1.get(ch);
if ( f1.eof() )
break;
if ( ch=='A' )
f2.write( (char*)&c,sizeof(c) );
else
f2.read( (char*)&c,sizeof(c) );
f1.read( (char*)&b,sizeof(b) );
}
f1.close();
f2.close();
rename("NEW.TXT","NOTES.TXT");
}

dosto please help .Rates assured !

In place of

while ( !f1.eof() )
{
f1.get(ch);
if ( f1.eof() )
break;

use
while (f1)
{

f1.get(ch); //and rest as same. so no need for break statement

// DUDE WAIT... it isn't completed.. i'm working on it

 

 

void countA()
{
char ch;
notes b; /*notes is a class previously defined in the program to
take the contents of NOTES.TXT */
int count = 0;
ifstream f1;

ofstream f2;
f1.open("NOTES.TXT",ios::in);
f2.open("NEW.TXT",ios::out);
if ( !f1 || !f2 )
{cout<<"FILE NOT OPENED!!!!!!!!!!";
exit(0);
}
else
{
f1.read( (char*)&b,sizeof(b) );
while (f1)
{
f1.get(ch);
if ( ch=='A' )
f2.write( (char*)&b,sizeof(b) );

f1.read( (char*)&b,sizeof(b) );
}
f1.close();
f2.close();
rename("NEW.TXT","NOTES.TXT");
}
