C++ Fundamentals

What is a struct in C++?

• A struct in C++ is a built-in data type for storing integers.

• A struct in C++ is used for defining functions.

• A struct in C++ is a keyword for loops.

• A struct in C++ is a user-defined data type that allows you to group different types of variables under one name.

Who developed the C++ programming language?

• Linus Torvalds

• Bjarne Stroustrup

• Tim Berners-Lee

• Dennis Ritchie

What are the different data types available in C++?

• int, float, double, char, bool, arrays, structures, classes

• string

• boolean

• pointers

• float

How can you perform iterations in C++?

• Iterations in C++ are done by using 'switch' statements.

• Performing iterations in C++ involves using 'goto' statements.

• You can perform iterations in C++ using 'if-else' statements.

• You can perform iterations in C++ using loops like 'for', 'while', or 'do-while'.

Why are structs used in C++?

• To perform mathematical operations efficiently

• To handle exceptions in the code

• To create user-defined data types that can hold multiple variables of different data types under a single name.

• To improve the readability of comments

When was C++ first released?

• 1985

• 2005

• 1975

• 1990

Give an example of a primitive data type in C++.

• double

• string

• float

• int

What is the syntax for a 'for' loop in C++?

• for(initialization; condition; increment) {}

• for(initialization; condition; decrement) {}

• for(initialization; condition; increment/decrement) {}

• for(initialization; condition; increment/decrement) ;

What is the significance of the 'auto' keyword in C++?

• It is used for type inference in C++.

• It is a deprecated keyword in C++.

• It is used for memory allocation in C++.

• It is used for defining global variables in C++.

What are the advantages of using C++ over other programming languages?

• C++ is not compatible with C code

• C++ offers high performance, strong hardware control, extensive libraries, and compatibility with C code.

• C++ has limited libraries

• C++ is slower than other languages
