a.
linking
b.
loading
c.
allocation
d.
reallocation
Correct Answer
Step-by-Step AI Explanation

Choose the option of task not performed by the macro processor
a.
Recognize macro definition
b.
Recognize calls
c.
Compile the macro
Correct Answer
d.
Expand calls and substitute arguments
Step-by-Step AI Explanation

(a) Static
(b) Automatic
(c) Controlled
(d) Block structure
1. Allows the programmer to control the space allocation
2. Scope of declaration of variables
3. Compile time
4. Storage is allocated when block is referenced
a.
(a)-4, (b)-1, (c)-2, (d)-3
b.
(a)-3, (b)-1, (c)-2, (d)-4
c.
(a)-3, (b)-4, (c)-1, (d)-2
Correct Answer
d.
(a)-4, (b)-2, (c)-1, (d)-3
Step-by-Step AI Explanation
Verified Method
In PL/I: Static storage is allocated at compile time (3); Automatic storage is allocated upon entering the block (4); Controlled storage allows programmer-driven allocation via ALLOCATE/FREE (1); Block structure controls variable scoping (2).
Q8mcq

a.
Weighted Graph
b.
Structured Graph
c.
Dependency Graph
Correct Answer
d.
Finite Graph
Step-by-Step AI Explanation
Verified Method
