Types of C Constants

Types of C Constants

C constants can be divided into two major categories:

  1. Primary Constants
  2. Secondary Constants

These constants are further categorized as shown in Figure 1.4.

At this stage we would restrict our discussion to only Primary Constants, namely, Integer, Real and Character constants. Let us see the details of each of these constants. For constructing these different types of constants certain rules have been laid down.
These rules are as under:

Rules for Constructing Integer Constants 
Rules for Constructing Real Constants 
Rules for Constructing Character Constants

          SQL Syntax:            SQL Syntax Database Tables A database contains one or more tables. Each table is identified by a name (e.g. "Student" or "Product").  Tables contain records (rows) with data.

Type Declaration Instruction in C

Type Declaration Instruction This instruction is used to declare the type of variables being used in the program. Any variable used in the program must be declared before using it in any statement. The type declaration statement is written at the beginning of main( ) function. Ex.: int bas ; float rs, grosssal ; char name, code ; There are several subtle variations of the type declaration instruction. These are discussed below: While declaring the type of variable we can also initialize it as shown below. int i = 10, j = 25 ; float a = 1.5, b = 1.99 + 2.4 * 1.44 ; The order in which we define the variables is sometimes important sometimes not. For example, int i = 10, j = 25 ; is same as int j = 25, j = 10 ; However, float a = 1.5, b = a + 3.1 ; is alright, but float b = a + 3.1, a = 1.5 ;         is not. This is because here we are trying to use a even before defining it. The following statements would work int a, b, c, d ; a = b = ...
