ALGORITHM

1) Start the process
2) Create the input file and out put file.
3) Get the input file name to fname1.
4) Get the output file name to fname2.
5) Open the infile(fanme1)
6) Check if infile.fail()
a) True:
i) Execute error conversion
ii) exit
7) open the outfile(fanme2)
8) check if outfile.fail()
a) repeat step(6:a)
9) check while infile.eof()
a) True:
i) Ch?(char)infile.get()
10) Close both files
11) Stop the process.

void main( )
{
	ofstream outfile;
	ifstream  infile;
	char fname1[10],fname2[20];
	char ch,uch;
	clrscr( );
	cout<<"Enter a file name to be copied ";
	cin>> fname1;
	cout<<"Enter new file name";
	cin>>fname2;
	infile.open(fname1);

if( infile.fail( ) )
	{
		cerr<< " No such a file Exit";
		getch();
		exit(1);
	}
	outfile.open( fname2);
		if(outfile.fail( ))
		{
			cerr<<"Unable to create a file";
			getch();
			exit(1);
		}
	while( !infile.eof( ) )
	{
		ch = (char) infile.get( );
		uch = toupper(ch);
		outfile.put(uch);
	}
	infile.close( );
	outfile.close( );
	getch( );
}

OUTPUT:

Enter a file name to be copied.
C:\text1.txt
Enter new file name
D:\new.txt

Input file
Asbcdefghijklmnopqrstuvwxyz
Output file
ASBCDEFGHIJKLMNOPQRSTUVWXYZ

ALGORITHM

1. Start the process
2. Invoke the class
a. Create two inline member functions .ie, getdata() and dispdata()
i. getdata() for input
ii. dispdata() for display
3. Open the file in fstream mode
4. Write the data in to the file
5. Slose the file
6. Stop the process

PROGRAM

#include
#include
#include
class student
{
private:
int rno;
char name[10];
float fees;
public:
void getdata()
{
cout<<"roll number";
cin>>rno;
cout<>name;
cout<>fees;
}
void dispdata()
{
cout<<"Roll number"<>wish;
}
while(wish=='y'||wish=='Y');
stdfile.close();   //close the file

getch();
}

OUTPUT

Roll number 121
Enter name Jacob
Enter fees 10000
