Smarter ways to define MACRO to strings?

[George2]

Hello everyone,


I have a number of strings in an array,

"FILE1", "FILE2", "FILE3", ... , "FILEN"

I want to add the common prefix to all the string, like

(for example, the common prefix is "FOO")

"FOOFILE1", "FOOFILE2", "FOOFILE3", ... , "FOOFILEN".

Are there any smarter ways to use a macro to define all of them altogether?


thanks in advance,
George

char prefix[] = "FOO", file[] = "file", emptyarray[strlen(prefix) + strlen(file) + 5];
int number = 1;

for(i; i <= 10; i++)
{
     sprintf(emptyarray, "%s%s%d", prefix, file, number);

     // .. do something ..
}
