renaming a file by c++

[ehsanelahimirza]

hi

plz tell me how to rename a file by using c++

i want to take path by user and want to take just new name without path

It can be done like this. Anyway this is not a good method.

#include "stdio.h"
#include "dos.h"
int main()
{
system("ren 6.txt 6666.txt");
}

This program will rename the 6.txt as 6666.txt. It is done with TurboC in windows.
The restiction here is that the file that is to be renamed must be in the TC folder.

If anyother method is there please let us know

Also you can use the function rename( )

here is an example:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    char old_name[20], new_name[20];
    
    cout<<"Enter filename: ";
    cin>>old_name;
    cout<<"Enter new file name: ";
    cin>>new_name;
    
    if(rename(old_name, new_name)==0)
    cout<<"Success\n";
    else
    cout<<"error";
    
    system("PAUSE");

    return EXIT_SUCCESS;
}

BOOL MoveFile(
LPCTSTR lpExistingFileName, // file name
LPCTSTR lpNewFileName // new file name
);

Hi saeid5977,
MoveFile is a win32 api and will work only on Windows OS and if we need to make it generic on different platforms,it better to stick with c++ Ansi runtime library calls.
