Que. Consider the program below in a hypothetical programming language which allows global variables and a choice of static or dynamic scoping
 
int i;
program Main( )
{
i = 10;
call f ( );
}
procedure f( )
{
int i = 20;
call g ( );
}
procedure g( )
{
print i;
}

Let x be the value printed under static scoping and y be the value printed under dynamic scoping. Then x and y are
a. x = 10, y = 20
b. x = 20, y = 10
c. x = 20, y = 20
d. x = 10, y = 10
Answer:x = 10, y = 10

Richa :(May 17, 2020) I think answer should be a. Becoz in dynamic scoping reference to the non-local variable is resolved from the calling parent, that way value of i in dynamic scoping should be fetched from the calling parent that is f().
