* Pointer to a variable  & Address of

(a)B/A (b) B%A

(a) false
(b) true.

(i) The '/' operator results in quotient when a number is divided by other number.
(ii) The'%' operator results in remainder when a number is divided by other number.

The multiple use of input and output operators such as >> and << in a single statement is known as cascading of I/O operators

All statements that being with // are treated as comments. Comments are simply ignored by compilers. i.e., compiler does not execute any statement that begins with a //.

The symbols which are used to do some mathematical and logical operations are called as "Operators". The data items or values that the operators act upon are called as "Operands".

Character set is the set of characters which are allowed to write a C++ program. A character represents any alphabet, number or any other symbol.

Characters enclosed in single quotes are character constants in c++ so 'a' is a  character constant. Character enclosed in Double quotes are strong constants in c++ so "a" is a string constant.

(a) 6
(b) False

double x = 10.5, y = 4.5;
int a;
a = int (x) + int (y);

56L- The suffix L forces the constant to be represented as long, which occupies 4 bytes.
56- This will be represented as int type constant which occupies 2 bytes as per Turbo C++.

(i) \(23.197=0.23197 \times 10^2=0.23197 \mathrm{E} 2\)
(ii) \(7.214=0.7214 \times 10^1=0.7214 \mathrm{E} 1\)
(iii) \(0.00005=0.5 \times 10^{-4}=0.5 \mathrm{E}-4\)
(iv) \(0.319=3.19 \times 10^{-1}=3.19 \mathrm{E}-1\)

C++ program statements are constructed by many different small elelments such as commands, variables, constants and many more symbols called as operators and punctuators. Individual elements are collectively called as Lexical units or Lexical elements or Tokens. C++ has the following tokens:
(i) Keywords
(ii) Identifiers
(iii) Literals
(iv) Operators
(v) Punctuators
