What is the function of a compound statement if it is not associated with a conditional? (if(), for(), while() etc.)

to... not compile.

With the exception of "for"; an omitted conditional will be replaced with "true".

If you mean something like:

{
//stuff
// something that isn't an if, while, etc.
{
// other stuff
}
}

Then the nested compound statement introduces a new scope. You can use it to make sure a temporary value you need is destroyed as soon as it isn't being used. Ex:

Mutex m("mutex name");
{
Lock l(m);
// stuff that needs to be done while the mutex is locked
}
// mutex is unlocked as as the scope is exited
