Programming

Question 43

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 static scoping and call by need parameter passing mechanism, the values printed by the above program are

Question 43 Explanation:

P(i+j)
P(100+5) = P(105)
→void P(105)
{
int i=10;
print (x+10); ⇒ 105+10=115 prints

i=200;

j = 20;

print (x); ⇒ x=105 prints

}
115, 105 prints

Correct Answer: D

Question 43 Explanation:

P(i+j)
P(100+5) = P(105)
→void P(105)
{
int i=10;
print (x+10); ⇒ 105+10=115 prints

i=200;

j = 20;

print (x); ⇒ x=105 prints

}
115, 105 prints
