What is the referencing environment at each of the four locations indicated for static scoping and dynamic scoping; i.e., which variables are visible and which procedures are they declared in (e.g., f.y, g.y, or h.y)?
Please explain the steps
Consider the following program in a C-like language that allows nested procedures. For static scoping, assume that a declaration is in force from the point it appears until the end of the block in which it appears. For dynamic scoping, assume that declarations are encountered during execution in the order they appear within a procedure. void main() int z = 10; void g() int x = 12; int y = 3; // location A void f() z = x*y; printLine(x, y, z); // location B void h() // locationc int y = 2; int z = 5; x = y+z; printLine(x, y, z) f(); h(); printLine(x, y, z); g ; // location D Consider the following program in a C-like language that allows nested procedures.
