create numbered files in C

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

char *filename = "file";
str开发者_如何学JAVAcat(filename, i); // put the number i at the end of the filename

Clearly that isn't the way to do it, but any ideas as to how I can accomplish this task?

Thanks,

Hristo

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

How about something like this?

char filename[256];
int i = 1;

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

You can use sprintf.
