These functions perform action and have no explicit return value.

This type of conversion is also called as user-defined type conversion as it is explicitly performed by user.

This function converts its argument to uppercase if the argument is in lowercase.

Formal parameters are the variables that receive the incoming values in a function.

These operators are used to carry out the comparisons among two operands.

This is the correct use of short hand operator to increment the variable on the left-hand side with some particular value.

The conditional operator is a ternary operator which requires three operands depending upon the condition specified. We also specify values to be assigned to the left-hand variable if the condition is true or false.

The default statement is optional and, if it is missing or not present, no action takes place if all matches fail.

The test expression is an expression whose truth value decides whether the loop-body will be executed or not.

Enumeration data type associates integer constants to names.

The process of containing objects of another class in a class is known as containership.

This function is used to find the absolute value of value given with the function.

Union data type shares same memory location by one or more different variables.

Reference variable is used in C++ to assign alternate name or alias to existing variable.

This operator cannot be overloaded in C++ to perform any additional function.

This statement is used to declare pre-processor constant statement in C++.

A constructor with arguments is called as parameterized constructor.

Function overloading means the use of same function name to perform different tasks.

This is the looping structure in C++ which excecutes its body until the condition specified in the while statement becomes false.

This is the function which is not in the scope of any class and acts as friend to all classes. 

In multiple inheritance, to avoid duplication of inherited members to the derived class, base classes are declared as 'virtual' base class.

Function scope is the scope of variable declared in outermost block of a function.

'Break' statement is used to exit from the loop statement in the program whereas 'Continue' is used to skip the specified iteration from the loop statement.

This header file is included to perform character functions like isalnum(), isdigit(), islower() etc. in the program.

Private members of a base class cannot be inheriated either by using public or private derivation.
