Copy Files in C++
To copy the content of one file to the other file in
C++ programming, you have to first ask to the user to enter the source file to open the source
file and then ask to enter the target file to open the target file and start reading the source
file's content character by character and place or write the content of the source file to the
target file character by character at the time of reading as shown here in the following program.
C++ Programming Code to Copy Files
Following C++ program ask to the user to enter the two file name.
First file name is source file (the content of this file is going to copy to the target file) and
the second name is target file (the content of the source file is copied to this target file).
After entering the two file name, the below program start copying the content of the source file
to the target file.
After copying it will output a message, file copied successfully :
/* C++ Program - Copy Files */
#include<iostream.h>
#include<conio.h>
#include<fstream.h>
#include<stdio.h>
#include<stdlib.h>
void main()
{
clrscr();
ifstream fs;
ofstream ft;
char ch, fname1[20], fname2[20];
cout<<"Enter source file name with extension (like files.txt) : ";
gets(fname1);
fs.open(fname1);
if(!fs)
{
cout<<"Error in opening source file..!!";
getch();
exit(1);
}
cout<<"Enter target file name with extension (like filet.txt) : ";
gets(fname2);
ft.open(fname2);
if(!ft)
{
cout<<"Error in opening target file..!!";
fs.close();
getch();
exit(2);
}
while(fs.eof()==0)
{
fs>>ch;
ft<<ch;
}
cout<<"File copied successfully..!!";
fs.close();
ft.close();
getch();
}
When the above C++ program is compile and executed, it will produce the following result:
After running the above C++ program, your target file will contain the source file's
content
