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; } i+=y; return get_2(9);}Using local classes, you’d do it like this:
int get_1 (int y){ int i = 9; class Local { public: int operator () (int h) { return r + h; } int r; }local; local.r = i + y; return local(9);}
