Question

Match the following types of variables with the corresponding programming languages :

$\begin{array}{clcl} \text{(a)} & \text{Static variable} & \text{(i)} & \text{Local variables in Pascal} \\  \text{(b)} & \text{Stack dynamic}& \text{(ii)} & \text{All variables in APL} \\   \text{(c)} & \text{Explicit heap dynamic}& \text{(iii)} & \text{Fortran 77} \\   \text{(d)} & \text{Implicit heap dynamic}& \text{(iv)} & \text{All Objects in JAVA} \\  \end{array}$

$\textbf{Codes :}$

• A. $\text{(a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)}$
• B. $\text{(a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)}$
• C. $\text{(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)}$
• D. $\text{(a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)}$

Answer 1

FORTRAN I, II, and IV contain only static variables

All objects in Java are explicit heap-dynamic variables and are destroyed by 'garbage collection'

Languages such as APL, ALGOL 68, and LISP use implicit heap-dynamic variables.

So, a- iii, c- iv, d-ii

Hence correct option is C
