Actually, in a C++ program I advice against using it (there used to be a reference to C which has been edited out by now, when I answered at first). 3. A sensible idiom for assigning values to leaves is leaf.value = leaf.project(val), ensuring that the assigned value satisfies the leafs properties.A slightly more efficient variant is leaf.project_and_assign(val), which projects and assigns the value directly, without additionally checking that the value satisfies the leafs properties.In most cases project and checking that a Do US public school students have a First Amendment right to be able to perform sacred music?
