C++ program statements are constructed by many different small elelments such as commands, variables, constants and many more symbols called as operators and punctuators. Individual elements are collectively called as Lexical units or Lexical elements or Tokens. C++ has the following tokens:
(i) Keywords
(ii) Identifiers
(iii) Literals
(iv) Operators
(v) Punctuators
4.
Header files contain definitions of Functions and Variables, which is imported or used into any C++ program by using the pre-processor #include statement. Header files have an extension ".h" which contains C++ function declaration and macro definition.
Example: #include<iostream.h>
5.
| Syntax error | Logical error |
| The syntax is a set of grammatical rules to construct a program. Every programming language has unique rules for constructing the source code. Syntax errors occur when grammatical rules of c++ are violated. | A Program has not produced the expected result even though the program is grammatically correct. It may happen by the wrong use of variable/operator/order of execution etc. This means, the program is grammatically correct, but it contains some logical errors. So, Semantic error is also called as "Logic Error". |
6.
| Run time error | Syntax Error |
| 1. A run time error occurs during the execution of a program. It occurs because of some illegal operation that takes place. 2. For example, if a program tries to open a file which does not exist, it results in a run-time error. |
1. Syntax errors occur when grammatical rules of C++ are violated. |
