GATE CSE 1990 | Question: 2-v

Question

Match the pairs in the following questions:$$\begin{array}{|ll|ll|}\hline (a) & \text{Pointer data type} & (p) & \text{Type conversion} \\\hline  (b) & \text{Activation record} & (q) & \text{Dynamic data structure} \\\hline   (c) & \text{Repeat-until} & (r)  & \text{Recursion} \\\hline (d) & \text{Coercion} & (s)  & \text{ Nondeterministic loop }  \\\hline \end{array}$$

Comments

Many programming languages support the conversion of a value into another of a different data type. This kind of type conversions can be implicitly or explicitly made. Implicit conversion, which is also called coercion, is automatically done. And the explicit conversion is known as Casting.

---

also coercion, is performed by the semantic analysis phase of the compilartion process 

Answer 1

$$\begin{array}{|ll|ll|}\hline (a) & \text{Pointer data type} & (q) & \text{Dynamic data structure} \\\hline  (b) & \text{Activation record} & (r) & \text{Recursion} \\\hline   (c) & \text{Repeat-until} & (s)  & \text{Nondeterministic loop} \\\hline (d) & \text{Coercion} & (p)  & \text{Type conversion}  \\\hline \end{array}$$

pointer is used for dynamic allocation of memory but how it is related to Dynamic data structure.

@rohith1001

thanks :)

Answer 2

coercion means changing an entity : so Type conversion d-p.

repeat untill - non deterministic loop c-s.

activation record means part of stack  :so recursion.

pointer data type :type conversion

Comments

how pointer data type :type conversion..???

---

Pointer data type is related to Dynamic data structure, I think that he might typed mistakenly.

Answer 3

d-p

b-r

a-q

c-s

Answer 4

 

A-Q, B-R, C-S, D-P
