Create numbered files in C

Question

I need to create files with the same name but with a number attached to the end of the file name to indicate that it was the nth file. So in the for loop, I basically want to do this:

char *filename = "file";
strcat(filename, i); // put the number i at the end of the filename

Clearly, this is not a way to do this, but any ideas on how I can accomplish this task?

Thank you
Christo

Answer 1

How about something like that?

char filename[256];
int i = 1;

// codes omitted...
sprintf(filename, "file%4d", i);

Answer 2

sprintf()or snprintf()using "file%d".

Answer 3

You can use sprintf.
