// Command line input: my_program.exe -c foo,bar -s 10 int main(int argc, char* argv[]) { CollectionOptions options = CollectionOptions::parse(argc, argv); // options.count() returns number of parsed options // options.getIn this example, the command line input specifies two options: `-c` and `-s`. The `-c` option takes in a comma-separated list of strings, and the `-s` option takes in an integer value. This function is a part of the C++ Boost library, specifically the program_options library.("c") returns the value "foo,bar" // options.get ("s") returns the value 10 return 0; }
