1.	We know that the value of pi = 3.14157, a constant (literal). What is a. constant? Explain it.
Answer» A constant or a literal is a data item its value doe not change during execution. 1. Integer literals: Whole numbers without fractional parts are known as integer literals, its value does not change during execution. There are 3 types decimal, octal and hexadecimal. Eg. For decimal “100, 150, etc For octal 0100, 0240, etc For hexadecimal 0 × 100, 0x1 A, etc 2. Float literals: A number with fractional parts and its value does not change during execution is called floating point literals. eg: 3.14157,79.78, etc 3. Character literal: A valid C++ character enclosed in single

Answer»

A constant or a literal is a data item its value doe not change during execution.

1. Integer literals:

Whole numbers without fractional parts are known as integer literals, its value does not change during execution.

There are 3 types decimal, octal and hexadecimal.

Eg. For decimal “100, 150, etc

For octal 0100, 0240, etc
For hexadecimal 0 × 100, 0x1 A, etc

2. Float literals:

A number with fractional parts and its value does not change during execution is called floating point literals.

eg: 3.14157,79.78, etc

3. Character literal:

A valid C++ character enclosed in single
