GATE CS 2022 : Compiler design Quiz -5

What is the output of following program?

// Parameters are passed by reference

main()

{

x = 10;

y = 5;

Fun(y,x);

Print(x);

Print(y);

}

Fun(a,b)

{

a= a - 5;

b = b + 10;

}

Block Structures, procedures and recursion can be handled in compiler by a

Compile Time stacks are not used for

Which of the following information is not available in the activation record of a procedure?

What is output by calling P in a language with static scope will be?

procedure P;

x: integer

procedure q;

begin

x = x + 1;

end;

procedure r;

x: integer;

begin x=5;

q;

write(x);

end;

begin //procedure starts here

x = 3;

r;

end;

How many times the activation record of the functions will be pushed – poped onto the stack for the execution of the following program?

int main()

{

int n , b;

printf("Enter the number");

scanf("%d",&n);

b= A(n);

printf("%d",b);

return 0;

}

A(int n)

{

if(n==1)

return 1;

else

return 1+A(n/2);

}

Where the value of n is entered as 512
