I would like to change a txt file's name, but I can not find how to do this.
For example, I want to rename foo.txt to boo.txt in my C++ program.

Open File Explorer by going to My Computer, or by pressing Windows Key + E on your keyboard. Find the file you want to rename, select it and select Rename on the ribbon (or press F2 on your keyboard). Type the new name you want the file to have and press Enter.
rename() function in Cint rename(const char * oldname, const char * newname); rename() function is defined in stdio. h header file. It renames a file or directory from oldname to newname .
The remove( ) function requires a C-style string as an argument. If an apstring type variable is used as an argument, you must engage the . c_str( ) to convert it to a standard C++ string variable. The rename( ) function takes the name of a file as its argument, and the new name of the file as a second argument.
rename() Prototypeint rename( const char *oldname, const char *newname ); The rename() function takes a two arguments: oldname , newname and returns an integer value. It renames the file represented by the string pointed to by oldname to the string pointed to by newname . It is defined in <cstdio> header file.
#include <stdio.h> (or <cstdio>) and use rename (or std::rename):
rename("oldname.txt", "newname.txt");
Contrary to popular belief, this is included in the standard library, and is portable up to a point -- though of course the allowable contents of the strings will vary with the target system.
