How do you do multiple options in C++?
Add a new . cpp file by going into project and selecting add new item. Start the file by writing “#include ” and “using namespace std;” at the top of the file. Add a void function prototype for the end of the program that will take an integer for the number correct.
How do you give a choice in C++?
You can refactor the switch into a function, which can be called whenever the player wants to change their difficulty choice. Now whenever the player decides to change difficulty (maybe they enter a special letter) you can use choice = choose() to alter the difficulty.
What is STD in C++ Mcq?
What is std in C++? Clarification: std is a standard namespace present in C++ which contains different stream classes and objects like cin, cout, etc. and other standard functions.

| Answer:Structures can have functions as members. |
How are multiple selections implemented in C?
Solution: C has two separate ways to get multiway selection enforced. The first is to use the ‘switch statement’. The other is a programming technique known as the else-if construct, which gives nested if statements a convenient style. Hence, the correct answer is (e), that is, else-if and switch.
What is multi way selection statement in C?
A multi-way selection statement is used to execute at most ONE of the choices of a set of statements presented. Syntax of the multi-way select statement: switch ( EXPRESSION ) { case CONSTANT1: one or more statements; break; case CONSTANT2: one or more statements; break; [ default: one or more statements;] }
What is selection structure in C++?
Also known as a conditional structure, a selection structure is a programming feature that performs different processes based on whether a boolean condition is true or false. Selection structures use relational operators to test conditions.

What does a class in C++ holds Mcq?
1. What does a class in C++ holds? Explanation: The classes in C++ encapsulates(i.e. put together) all the data and functions related to them for manipulation.

| Q. | Which of the following is FALSE about references in C++ |
|---|---|
| A. | a reference must be initialized when declared |
| B. | once a reference is created, it cannot be later made to reference another object; it cannot be reset |
| C. | references cannot be null |
| D. | references cannot refer to constant value |
Which is multiple selection statement in C?
C has two different ways to implement multiway selection: the switch statement and else-if construct. One of the assets of the C language is its rich set of standard functions that make programming much easier. For example, C99 has two parallel but separate header files for manipulating characters: ctype. h and wctype.
What is multiple selection structure?
Occasionally, an algorithm contains a series of decisions in which the algorithm tests a variable or expression separately for each value that the variable or expression might assume. The algorithm then takes different actions based on those values.
What are the selection structures found in C++?
Control Structures – Selection
- Sequential: default mode; Executed line by line, one right after the other.
- Selection: decisions, branching; When there are 2 or more alternatives. Three types:
- Repetition: used for looping, or repeating a section of code multiple times. Three types:
What is multiple selection statement?
1. switch Multiple-Selection Statement. Occasionally, an algorithm will contain a series of decisions in which a variable or expression is tested separately for each of the constant integral values it may assume, and different actions are taken. This is called multiple selection.
What is two-way selection in C++?
Two-way selection takes the form: If expression is true, statement1 is executed; otherwise, statement2 is executed o statement1 and statement2 are any C++ statements else is a reserved word.
Why is C++ called C++?
C++ is a general-purpose object-oriented programming language developed by Bjarne Stroustrup of Bell Labs in 1979. C++ was originally called ‘C with classes,’ and was built as an extension of the C language. Its name reflects its origins; C++ literally means ‘increment C by 1. ‘
How do I put Iostream in C++?
To use cin and cout in C++ one must include the header file iostream in the program….Header files available in C++ for Input/Output operations are:
- iostream: iostream stands for standard input-output stream.
- iomanip: iomanip stands for input-output manipulators.
What is the difference between delete and delete in C++ Mcq?
12. What is the difference between delete and delete[] in C++? Explanation: delete is used to delete a single object initiated using new keyword whereas delete[] is used to delete a group of objects initiated with the new operator.
What is the difference between struct and class in C++ Mcq?
What is the difference between struct and class in C++? (B) Members of a class are private by default and members of struct are public by default. When deriving a struct from a class/struct, default access-specifier for a base class/struct is public and when deriving a class, default access specifier is private.
