C++ Interview Question and Answers Part 12

 

111.What are different types of Comments in C++ and explain each of them?

  • There are two types of comments in C++ Programming language.

    1. Single line comment.

    2. Multi line comments.

Single line comment

  • Single line comments is accomplished by double-slash (//).

  • Everthing that is followed by double-slash till the end of line is ignored by the compiler.

  • It is reffered as C/C++-style comments as it is originally part of C/C++ programming.

  • start with double slash symbol (//) and terminate at the end of the line.

Multi line comment

  • Multi-line comments starts by using forward slash followed by asterisk (/*) and ends by using asterisk followed by forward slash (*/).

  • Everthing between (/*) and (*/) are ignored by compiler whether it is one or more than one line or a block of code.

  • It is reffered as C-Style comment as it was introduced in C programming. But later on this comments where added in C++.

 

112.What are C++ Constants or Literals?

  • Constants or Literals are data with fixed or known value.

  • In C++, Constants is entity that doesn't change.

 

113.What are Types of Constants and explain each of them in?

  • There are three types of Constants.

    1. Integer Constant

    2. Real Constant

    3. Character Constant

Integer Constant:

  • An Integer constant must have at least one digit and no decimal point.

  • Can be either Positive or Negative, number without sign is considered as Positive.

  • Commas or Blank are not allowed.

  • Values for Integer Constant can range from -32768 to 32767.

  • For example 121, 4100, -7500

Real Constant:

  • Real Constant can be in form of Fractional or Exponential format.

  • Must have at least digit and Decimal Point.

  • Can be either Positive or Negative, number without sign is considered as Positive.

  • Commas or Blank are not allowed.

  • For example 125.75, -211.15, 560.01 etc.

  • In Exponential format, it has two parts, mantissa and Exponent. Both are separated by letter E or e. Mantissa is either integer or real and Exponent must be integer. (For e.g. 1.25E6,-0.5e+3, 4.1e-5 ).

Character Constant:

  • Character constant is a single alphabet, a single digit or special symbol enclosed within single inverted commas.

  • Maximum length of character constant is only 1 character.

  • For example 'a', 'E', 'S', '+', '?'

 

114.What is Variables in C++?

Variable are placeholder to store values. Also called as identifiers.

As value varies from time to time, it is called variable.

Variable names are name given to location in memory. Those memory location can contain integer, real or character data.

Every variable is identified by a unique name.

 

115.Explain Operators and different types of Operators in C++?

  • The variables, which are declared and defined, are the operands which are operated upon by the operators.

  • Operators specify what operations are to be performed on the operands.

  • Some operators require two operands, while few operators require only one operand.

  • C++ includes many operators, which fall into different categories as follows.

ARITHMETIC OPERATORS

UNARY OPERATORS

RELATIONAL AND LOGICAL OPERATORS

ASSIGNMENT OPERATORS

CONDITIONAL OPERATORS

 

116.What is While Loop Statement in C++?

  • When a loop is described with a while statement , you can only specify the looping condition.

  • It is an entry controlled loop.

  • If the result of loop condition is true then the loop block is executed.

  • When the result of loop condition become false, it executes next statements, written after block scope.

 

117.What is do…while loop statement in C++?

  • The do-while statement is different from while because it first executes the statement blocks and then checks the condition.

  • It is an exit controlled loop.

  • Thus the loop is executed at least once, irrespective the condition is true or false. Where as in do statement, it check the condition first, and if result of condition is true, statement block will be executed.

118.What is goto Statement in C++?

  • Goto statement is used for branching to another part of program.

  • With the help of goto statement we can pass control to another statement within program.

 

119.How break and Continue Statement is done in C++?

  • Break and continue statement is use for, do, do..while loop for all iterations.

  • In normal operation, loop is terminated when condition become false.

  • Inside a loop flow can be controlled using break and continue.

  • Loop block continue various statements. When program executes continue statement, it will skips over the rest of statement in the loop, and control goes on to the beginning of loop.

  • Inside loop block, when program control executes break statement, the current loop is terminated abruptly, it comes out of loop forever.

  • This feature is used within loop for two termination points. One when condition is false and second when it comes across break statement within loop.

 

120.What is Arrays in C++?

A Variable store only one value.

  • Where is Array helps to store several value of same data type under single variable name.

  • An array is a set of related data items i.e. all of them belong to the same data type and can be accessed by a common name.

  • An array is a derived data type.

  • An array in C++ Programming Language can be defined as number of memory locations, each of which can store the same data type and which can be references through the same variable name.

  • Thus an array is a collection of similar elements. These similar elements could be all integers, all floats or all characters etc.
