If you want to make your application which works according to the location of the user, then this article is for you.

First, make a structure pointer which will point to structure object of lconv. Then, set your locality by calling setlocale(category, string).

In most cases, using LC_ALL as the category would be enough and passing the empty string for the second parameter will set everything as default.

Third thing is to get the address or the reference of the object and store it inside out locale pointer variable.

Finally, we have this awesome structural object ready to be used. You can get many things out of it, here is the list.
