Application Security Testing: An Integral Part of DevOps

Use Local Classes to Implement Nested Functions in C++

C++ does not support the nested functions. However, you can use local classes to simulate the effects of nested functions.

Take the scenario given below:

int get_1 (int y)
	int i = 9;

	int get_2(int j)
		return j + i;


	return	get_2(9);
Using local classes, you'd do it like this:

int get_1 (int y)
	int i = 9;
	class Local
		int operator () (int h)
			return r + h;
		int r;

	local.r = i + y;

	return local(9);
