Question

Use the following code to perform the following tasks:
1. Show all variables that are visible at POSITION #1 only. Provide their nesting level and offset, using the activation record layout discussed in class.S2how the contents of the call stack at the time when control reaches POSITION #1. Use the layout defined in chapter 10 and used in class for statically scoped languages that allow nested functions. Show values and links.

function main() {
int w = 1, x = 2;

function a(bool flag) {
int x = 3;

function b() {

c(4);

}

function c(int x) {
// POSITION #1

}

b();

}

a(true);

}
