C Compound Data Types Practice Problems

Compound Data Types are those data types in C that are created using basic data types. They provide an interface to use the built-in data types is different ways to satisfy our requirement. They are frequently used to handle real world cases it is a must for programmers to have good clear understanding.

Solving practice problems is the best way to improve your knowledge and familiarity of the concepts. This article lists a variety of practice problems based on compound data types such as arrays, pointers, strings, structures, etc.

Easy Problems

Easy problems only require the basic knowledge of compound data types. Following are some of the basic practice problems for C compound data types:

• Size of an Array
• Print Array
• Print Array in Reverse
• Array Insert at End
• Count Smaller Than X
• Sum of All Array Elements
• Largest Element in Array

Medium Problems

Medium problems have increased difficulty in which other topics are combined together with compound data types. This generally contains the common practical uses of compound data types in programming. Some of them are listed below:

• Increment Variable using Pointer
• Print Address of Variable
• Array Insert at Index
• First Repeating Element
• Reverse String
• Anagram
• Struct Area
• Add Two Complex Numbers
• Implement Union
• Maximum in Struct Array
• Self-Referencing Structures
• Swap Numbers using Function
• 2D World Representation

Prerequisite

The following practice problems are mainly about compound data types but also uses some basic concepts. Following are the concepts you should be familiar before you start solving these problems:

• Input/Output
• Data Types and Variables
• Operators
• Control Statements
• Functions
• Array
• Strings
• Pointers
• Structures
• Unions

Refer to our C Tutorial if you want to revise these concepts.

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.

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.
