C++ Compound Data Types Practice Problems
Last Updated :
09 Apr, 2025
C++ Compound data types are those data types that are created from in-built data types to provide a different way to use them. They are created to suite the need of a particular task in which the in-built data types fall short.
Practicing problems is one of the most effective ways to improve programming fluency in any language. This article provides a structured way to master key compound data types in C++ such as arrays, pointers and references, strings, structures, etc.
Easy Problems
These problems are the absolute basics of compound data types and mainly focuses on demonstrating their basic operations.
Medium Problems
Medium problems require the implementation of compound data types in some simple practical applications. It generally includes problems that builds your intuition of where you can use these datatypes.
Hard Problems
These problems require the complete understanding of these data types. These generally contains complex problems that also includes the use of other concepts.
Prerequisite
You must have the knowledge of the following concepts along with compound data types to solve these problems:
- Variables and Data Types
- Input and Output
- Operators
- Control Statements and Loops
- Functions
- Array and Strings
- Pointers and Strings
- Structure and Unions
It also requires the basic mathematical knowledge. If you want to revise these concepts, refer to GeeksforGeeks' C++ Tutorial.
How to solve practice problems?
Each of the above link will take you to the practice portal where the problem statement tells you all the required information about the problem, and you have to write the solution in the code editor.
Screenshot of Code EditorOnce your solution is complete, you can check it for example test case using the compile and run button at the bottom right of the page.
Editor ControlsIf you are sure of your solution, press the submit button. The GfG's compiler will run your solution for a variety of test cases and if all these cases are passed, you solution will be accepted.
Your own custom cases can also be checked before submission by using Custom Input button but keep in mind to follow the program's input layout.

Stack and Queue C/C++ Programs The stack and queue are popular linear data structures with a wide variety of applications. The stack follows LIFO (Last In First Out) principle where the data is inserted and extracted from the same side. On the other hand, the queue follows FIFO (First In First Out) principle, i.e., data is insert

Difference Between Struct and Typedef Struct in C++ In C++, the struct keyword is used to define a struct, whereas the typedef keyword is used for creating an alias(new name) for existing datatypes and user-defined datatypes like class, struct, and union to give them more meaningful names. In this article, we will learn the differences between a stru

C++ Compound Data Types Quiz Built-in data types cannot store all the information in an easily accessible and organized way. That is why C++ provides compound data types such as arrays, pointers, strings, etc. that are derived from the built-in data types and provide different way to use them.
