sprintf

[smart1seo]

what is the exact meaning of each word in the following?

sprintf(filenam e, "%s/cn_norms.xmrg", datadir);
i = read_xmrglike(f ilename, cn);


Is 'datadir' supposed to be a directory that file 'cn_norms.xmrg' should be located?

Carefully read your documenetation for sprintf.

sprintf is used to create strings and has nothing to do with files.

The code you have posted makes no sense.
