Getting Started :
C++ character set, C++ Tokens (Identifiers, Keywords, Constants, Operators), Structure of a C++
Program (include files, main function), Header files - iostream.h, iomanip.h, cout, cin; Use of I/O
operators (<< and >>), Use of endland setw (), Cascading of I/O operators, Error Messages; Use of
editor, basic commands of editor, compilation, linking and execution.
Data Types, Variables and Constants:
Concept of Data types; Built-in Data types: char, int, float and double; Constants: Integer Constants,
Character constants - \n, \t, \b), Floating Point Constants, String Constants; Access modifier: const;
Variables of built-in data types, Declaration/Initialisation of variables, Assignment statement; Type
modifier: signed, unsigned, long
Operator and Expressions :
Operators: Arithmetic operators (-,+,*,/,%), Unary operator (-), Increment (++) and Decrement (--)
Operators, Relation operator (>,>=,<,<=,= =,!=), Logical operators (!, &&,||), Conditional operator:
<condition>? <if true>:<else>; Precedence of Operators; Automatic type conversion in expressions,
Type casting; C++ shorthands (+=, -=, *=, /=, %=)
General Concepts; Modular approach; Clarity and Simplicity of Expressions, Use of proper Names
for identifiers, Comments, Indentation; Documentation and Program Maintenance; Running and
Debugging programs, Syntax Errors, Run-Time Errors, Logical Errors
Problem Solving Methodologies: Understanding of the problem, Identifying minimum number of
inputs required for output, Writing code to optimizing execution time and memory storage, step by step
solution for the problem, breaking down solution into simple steps, Identification of arithmetic and
logical operations required for solution, Control Structure: Conditional control and looping (finite and
Flow of control:
Conditional statements: if-else, Nested if,, Nested, break statement
(to be used in only); Loops: while, do - while , for and Nested loops
