The following questions refer to the skeletal C++ program shown below a. Assume that static scoping is used. List all variables, along with the functions in 4. which they are declared, that are visible at Line 1 in the program. Repeat part (a), but list the variables along with the functions in which they are declared that are visible at Line 2 Repeat part (a), but list the variables along with the functions in which they are declared that are visible at Line 3. Repeat part (a), but list the variables along with the functions in which they are declared that are visible at Line 4 Assume that dynamic scoping is used, and that main calls f2, which calls fl (Assume that f2 calls fl on Line 5.) List all variables, along with the functions in which they are declared, that are visible at Line 2 in the program. b. c. d. e. void fl void f2 0 int b, c, d; int main() ( int a, b, d; // Line 1 void fl) int d, e; //Line 2 int a, b; // Line 3 void f2) int a, c; int b, c; // Line 4 // Line 5 Here's an example of the format that vou should use for vour answers: b (global), d (declared in fl), e (declared in if block in f1)
