Instructions to write C Program

C Instructions


Now that we have written a few programs let us look at the instructions that we used in these  programs. There are basically three types of instructions in C:
  1. Type Declaration Instruction
  2. Arithmetic Instruction
  3. Control Instruction

The purpose of each of these instructions is given below:

     Type declaration instruction
To declare the type of variables used in a C program.
           Arithmetic instruction
To perform arithmetic operations between constants and variables.
           Control instruction
To control the sequence of execution of various statements in a C program.


Since, the elementary C programs would usually contain only the type declaration and the arithmetic instructions; we would discuss only these two instructions at this stage. The other types of instructions would be discussed in detail in the subsequent chapters.

          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. Below is a selection from the " Student " table: StudentID             StudentName               Address                Country 1             Ajay               Noida                India 2             Ajeet               Bareilly                India 3             Shivam               Nagaland...

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 = ...

          SQL Commands                       The SQL commands to interact with relational databases are: CREATE,  SELECT,  INSERT,  UPDATE,  DELETE and  DROP.               These commands can be classified into groups based on their nature:           DDL - Data Definition Language.            DML - Data Manipulation Language.            DCL - Data Control Language.
