C++ Fundamentals Practice Problems

Last Updated : 10 Apr, 2025

Fundamental concepts form the foundation of learning any programming language. They include absolute basic topics such as storing and accessing data, input and output, performing mathematical, logical, operations, etc. So it is important to have clear understanding of fundamentals to move on to the more complex concepts.

Solving practice problems is the best way to improve programming skills in C++. This article provides you practice problems to help learners build a strong foundation.

Easy Problems

These problems are the basic demonstrations of fundamental concepts and their basic usage.

Medium Problems

Problems in this section focuses on using the fundamental concepts to solve some simple real world problems. It may also need the knowledge of basic mathematical concepts.

Prerequisite

To solve the above problems, you need to have some basic understanding of C++ fundamentals:

Variables and Data Types
Operators
Input and Output
Conditional Statements
Loops

If you want to revise these topics, 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.

Once 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.

code-editor-controls — Editor Controls

If 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.
