This document provides an introduction to the C++ programming language. It discusses that C++ was developed by Bjarne Stroustrup and is a general-purpose, object-oriented language used for systems software, games, applications and scientific computing due to its efficiency and performance. The document then covers C++ syntax, variables and data types, operators, conditions, loops, and arrays. It explains how to declare and use variables, arrays, basic data types, operators, control structures like if/else statements and loops.

3. Introduction
• Developed by Bjarne Stroustrup
• General-purpose, Object-Oriented programming language
• Templates, Exception Handling, and Standard Template Library
• Efficiency, Performance, and Versatility
• System Software, Video Games, Desktop/Mobile Application,
High-performance scientific and engineering applications

4. Syntax
#include <iostream>
using namespace std;
int main(){
// Comments
cout<<"Welcome to C++“;
return 0;
}

5. Variables & Data Types
Data Types:
Data types are declarations for variables which determines
the type & size of data associated with variables
 Integer, Floating, Double, Character
Variables:
The names you give to computer memory locations which
are used to store values in a computer program
 int myVariableName = 10

6. Operators
• Arithmetic Operators
• Assignment Operators
• Comparison Operators
• Logical Operators

7. Conditions
• If Statements
• IF Else Statements
• Else If Statements
• Ternary Operator
• Switch Conditions

10. LOOPS
• For loop
• While loop
• Do While Loop

11. Arrays
• Arrays are consecutive group of memory consisting of same
types. We call the individual variables in an array the
elements of array. Each element is identified by an index
which denotes the position of the element in the array
• The number of elements in an array is called its length. The
length of an array is fixed and predetermined; it cannot be
changed during program execution

12. Array Cont..
When declaring arrays, specify
Name
Type of array
Number of elements
arrayType arrayName[numberOfElements];
• Examples:
int Array1[ 10 ];
float myArray[ 34 ];

13. To refer to an element, specify
• Array name
• Position number
Format:
arrayname[ position number ]
• First element at position 0
• n element array named c:
• c[ 0 ], c[ 1 ]...c[n – 1]
Name of array
Position number
of the element
within array c
