Programming

Question 41

The following program fragment is written in a programming language that allows variables and does not allow nested declarations of functions.

global int i = 100, j = 5;
void P(x)
{
    int i = 10;
    print(x + 10);
    i = 200;
    j = 20;
    print(x);
}
main()
{
    P(i + j);
}

If the programming language uses dynamic scoping and call by name parameter passing mechanism, the values printed by the above program are:

Question 41 Explanation:

In dynamic,
In void P(x)
{ int i = 10;

print(x + 10); ⇒ 105+10 = 115 prints

print (x); ⇒ print x=220;

Correct Answer: A

Question 41 Explanation:

In dynamic,
In void P(x)
{ int i = 10;

print(x + 10); ⇒ 105+10 = 115 prints

print (x); ⇒ print x=220;
