Basic syntax in C/C++.

Basic Syntax tells as about all the general points which we have to know/include in all the programs irrespective of whether the program is of few lines or it is of hundreds of lines.


In C++, semicolon is a statement terminator. That is each individual statement must be ended with a semicolon. It indicates the end of one logical entity.


For example:


x = y;


 A block is a set of logically connected statements that are surrounded by opening and closing braces. For example:


{ x=2; y=x; }

The Basic Syntax:-  it is very important to keep in mind the following points.

  1. Case Sensitivity - Java is case sensitive, which means identifier Hello and hello would have different meaning in Java.
  2. Class Names  - For all class names the first letter should be in Upper Case. If several words are used to form a name of the class, each inner word's first letter should be in Upper Case.        

          Example class MyFirstJavaClass

     3.  Method Names - All method names should start with a Lower Case letter. If several words are used to form the name of the method,           then each inner word's first letter should be in Upper Case.

          Example public void myMethodName()

     4.  Program File Name - Name of the program file should exactly match the class name. When saving the file, you should save it using the           class name (Remember Java is case sensitive) and append '.java' to the end of the name if the file name and the class name do not                   match your program will not compile.

          Example : Assume 'MyFirstJavaProgram' is the class name. Then the file should be saved as''

      5. public static void main(String args[]) - Java program processing starts from the main() method which is a mandatory part of every           Java program.
