is a programming language developed in 1980 by Bjarne Stroustrup at the Bell
Telephone Laboratories. C++ is object oriented programming language and it is a
very simple and easy language, this language have following
features:\nSimple\nPortability\nPowerful\nPlatform dependent\nObject
oriented\nCase sensitive\nCompiler based\nSyntax based language";

is an identifier whose value can not be changed at the execution time of
program. In general constant can be used to represent as fixed values in a C++
program.\n\n\n\t\t\t\tVariable\n\nVariable is an identifier which holds data or
another one variable is an identifier whose value can be changed at the
execution time of program. Variable is an identifier which can be used to
identify input data in a program.";

solution to any computing problem involves executing a series of actions in a
specific order. A procedure for solving a problem in terms of\n\t1. the actions
to be executed\n\t2. the order in which these actions are to be executed\nis
called an algorithm.\n\n\n\t\t\t\tPseudocode\n\nPseudocode is an artificial and
informal language that helps you develop algorithms. Pseudocode is similar to
everyday English; it?s convenient and user friendly although it?s not an
computer programming language.\n\n\n\t\t\t\tFlow Chart\n\nA flowchart is a
graphical representation of an algorithm or of a portion of an algorithm.
Flowcharts are drawn using certain special-purpose symbols such as
rectangles,diamonds,rectaingles,and small circles connected by
flowlines.";

statement. It tells to program to execute a certain part of code only if
particular condition or test is true.If the body is not specified, then
automatically condition part will be terminated with next semicolon ( ;
).\n\n\n\t\t\t\tIf...Else Statement\n\nIn general it can be used to execute one
block of statement among two blocks, in C++ language if and else are the
keyword in C++.whenever condition is true all the if block statement are
executed remaining statement of the program by neglecting else block statement.
If the condition is false else block statement remaining statement of the
program are executed by neglecting if block statements.";

Loops\nSet of instructions given to the compiler to execute set of statements
until condition becomes false is called loops. The basic purpose of loop is
code repetition that means same code repeated again and again. \nThere are
three type of Loops available in 'C' programming language.\n\t1: while
loop\n\t2: for loop3: \n\t3:do-while \n\n\t\t\t\tWhile Loop\nIn while loop
First check the condition if condition is true then control goes inside the
loop body other wise goes outside the body.
If while loop condition never false then loop become infinite
loop.\n\n\t\t\t\tFor Loop\nWhen you need to execute a block of code several
number of times then you need to use looping concept in C++ language. In C++
Programming Language for loop is a statement which allows code to be repeatedly
executed. For loop contains 3 parts whic are Initialization, Condition and
Increment or Decrements\n\n\t\t\t\tDo While loop\nA do-while loop is similar to
a while loop, except that a do-while loop is execute at least one time. A do
while loop is a control flow statement that executes a block of code at least
once, and then repeatedly executes the block, or not, depending on a given
condition at the end of the block (in while).";

in C++\n\n\nA function is a group of statements that together perform a
specific task. Every C++ program has at least one function, which is
main().\nFunction are used for divide a large code into module, due to this we
can easily debug and maintain the code. For example if we write a calculator
programs at that time we can write every logic in a separate function (For
addition sum(), for subtraction sub()). Any function can be called many
times.";

Statement in c++\n\nThe switch statement in C++ language is used to execute the

statement. A switch statement work with byte, short, char and int primitive
data type, it also works with enumerated types and string but not with

array is a collection of similar data type value in a single variable. It is a
derived data type in C++, which is constructed from fundamental data type of
C++ language. To declare an array in C++ required type of array elements and
size of array. Initializing is a process to initialize the value in array
variable. We can access array elements with the help of index value of
element.";

in C++\n\nString is a collection of character or group of character, it is
achieve in C language by using array character. The string in C language is
one-dimensional array of character which is terminated by a null character
'\0'. In other words string is a collection of character which is enclose
between double cotes ( " " ).\n\nNote: Strings are always enclosed
within double quotes. Whereas, character is enclosed within single quotes in
C.\n\nIn declaration of string size must be required to mention otherwise it
gives an error.";
