Object Oriented Programming - Basics of C++

1:  

C++ was originally developed by; 

A.

Clocksin and Mellish

B.

Donald E. Knuth

C.

Sir Richard Hadlee

D.

Bjame Stroustrup

 
 

Option: D

Explanation :


2:  

cfront

A.

is the front end of a C compiler

B.

is the pre-processor of a C compiler

C.

is a tool that translates a C++ code to its equivalent C code

D.

none of the above

 
 

Option: C

Explanation :

When C++ was developed. it did not have a compiler. It used cfront, which translated the C++ code into a C code and then the existing C compiler was used to compile the program originally written in C++.


3:  

Which of the followinig are procedural languages?  

A.

Pascal

B.

Smalltalk

C.

C

D.

Both(a) and (c)

 
 

Option: D

Explanation :

Procedural languages sequentially execute a set of imperative statements to achieve the desired
effect. Most of the traditional languages fall in this category.


4:  

Reusability is a desirable feature of a language as it

A.

decreases the testing time

B.

lowers the maintenance cost

C.

reduces the compilation time

D.

Both (a) and (b)

 
 

Option: D

Explanation :

Reusable code is an already used code, as the name implies. Hence it is bug-free and pre-tested.
There is no need to test it.


5:

C.

Operator precedence cannot be changed.

D.
