WebDec 5, 2024 · If you use a set, make sure to use set's find function (e.g. mySet.find (tableNum) rather than std::find (mySet.begin (),mySet.end (),tableNum) ), or there's no benefit. On a more general code-style note, since you're using C++ data structures anyway, you should probably use std::string and std::cout instead of char * / char [] and printf.
