Nested function
A nested function is a function which can only be called from its parent function. That is, the scope of the nested function is limited to the current function only. For instance, assuming that C supports nested functions (which it does not):
void foo() {
void bar() {
/* do something */
};
bar();
}
In this case bar is a nested function for foo and can only be called from foo.
Nested functions are useful for creating code blocks that must remain logically separate but are only useful for a specific function as opposed to the entire module or program.
