How do function objects contribute to metaprogramming capabilities in statically-typed languages?

Question 5 D In c++, cstring is implemented as an array of charaters. what is the difference between cstring and a regular array of characters? In other words how do you distinguish them?

Suppose that a programming language uses dynamic scoping. Consider the following code segment in C-like syntax. void func1(void); /* prototype */ void func2(void); /* prototype */ void func3(void); /* prototype */ void main() { int a, b, c; ... } void func1() { int b, c, d; } void func2() { int c, d, e; } void func3() { int d, e, f; } For each of the following calling sequences, determine which variables are visible during the execution of the LAST function called. In your answer, include, for each visible variable, the name of the functions in which it is declared. (1) main → func1 → func3→ func2 (fun2 is the last function called) (2) main → func2 → func3 → func1 (funl is the last function called)
