Chapter 3, Problem 3E

Program Plan Intro

Rules for constants:

Integer constants:

The integer constants can be decimal, octal or hexadecimal constants can only have numbers (0 – 9), non-real numbers. It can also have suffix that is a combination of “L” and “U” for long and unsigned respectively.

Floating point constants:

The floating point constants have an integer, decimal, fractional and exponent values. The user can represent floating point variables either decimal or exponential form.

Character constants:

The character constants are enclosed in single quotes. It can be an escape sequence, plain character or universal character.

String constants:

The string constants are enclosed in double quotes. It contains characters that are similar to character constants ie., escape, plain and universal sequence. The user can break the long line into many lines using string constants and separating them using blank spaces.
