The Best Exercises and Quizzes to Help You Learn Programming
Coding and programming careers tend to pay very well and maintain a high demand through a variety of industries. However, learning to code takes a lot of time, practice, and effort. Although coding bootcamps and courses act as excellent methods for learning to program, hands-on learning strategies, such as programming exercises, are a great way to develop coding skills quickly.
In this article, you’ll learn about some of the best programming exercises that will develop or sharpen your skills. You’ll also find some excellent resources that will guide you along your programming journey. To learn more about how you can get help with programming, read on.
Programming Exercises to Help You Learn Programming
One of the best ways to master programming is through practice and repetition. As a beginner, it is best to throw yourself into the deep of coding by trying out real exercises to build your problem-solving abilities. Below are some coding exercises that will help you become a pro at programming.
10 Programming Exercises and Practice Problems (With Solutions)
1. Write Basic Declarations and Expressions in C Basic
C is an easy language to learn. One of the entry-level exercises you should do in this language, especially as a beginner, is to write a C program to print your name, mobile number, and date of birth.
Solution: Open your programming software. Create and save a new file called myname.c. Use the getch (): and clrscr (): functions to read characters from the screen and remove those old/ preview output/ results values respectively.
2. Write a Java Program to Get a Number From the User
This programming exercise is designed to test your understanding of Java conditional statements. You should get a number from the user and print whether it is a positive or negative number. Java supports the typical logical conditions in math. You can use these conditions to perform actions for different decisions.
Solution: Use ‘if’ if a specified condition is true, ‘else’ elsewhere the condition is false, ‘else if’ if the first condition is false, and ‘switch’ when many alternative codes need to be executed.
3. Create a List by Picking an Odd-Index Item from the First List
Using Python, you can write a program to create a list from two given lists. This created list should feature an odd index element from one list and even index elements from the second one. This exercise is designed to test your understanding of data structures in Python.
Solution: Approach this question using List Slicing. It implies accessing a wide range of elements in a given list. The syntax for list slicing is listname[start_index : end_index : step]
4. Write a Program That Will Find Numbers Divisible by Seven But Not a Multiple of Five
This is a Python programming exercise designed to test a beginner’s understanding of this programming language. Similar challenges like this are listed in GitHub’s Python programming exercises. The numbers you find should be between 2,000 and 3,200.
Solution: Check whether each number is divisible by seven, but not divisible by five. To do this, you’ll have to perform 1201 checks. Consider using the range method (#begin #end)
5. Define a Class that Has at Least Two Methods (getString and printString)
This exercise is designed to test your basic comprehension of Python. This language has a built-in string class known as Strings (newly changed to ‘str’) which has a variety of features. They are immutable, meaning they can’t be changed after being created.
Solution: Construct some parameters using the _init_ method.
6. Create an Algorithm That Generates All Prime Numbers From O – N
Give this question a shot if you’re an advanced learner or confident in your programming abilities. This is designed to test your knowledge of algorithms and the Sieve of Eratosthenes. The Sieve of Eratosthenes is one of the most efficient and clever ways to find all prime numbers smaller than n.
7. Write Your Own Square Root Function
Find the square root of an integer. According to Geeks for Geeks, there are many ways of solving this including the Babylonian method which starts with an arbitrary positive start value. Initialize y=1 and get the approximation root for using average x and y.
Solution: A simple approach involves finding the floor of the square root, with all natural numbers. Start with one and work your way up until the square is greater than the given number.
9. Create an Empty Vector in R
This is an ideal exercise for learners who are new to R. Vectors are some of the simplest data structures in this language. They involve sequences of elements of the same basic type which can be integers or characters. Complicated data structures are made with vectors.
Solution: There are five ways to go about this. You can use c() with the syntax vector name <- c(), use vector () with the syntax vector name <- vector(), or use the numeric () method with the syntax vector name <- numeric()
10. Build A Web Scraper in Python
A web scraper is a program used to gather information from the Internet. Web scraping is helpful as it can help you extract all sorts of data and use it however you want. It simplifies the process of extracting data and creates easy access to scrapped data.
Solution: You can use Python to scrape any site of the Internet but consider the difficulty involved with doing so. Your web scraper should parse the HTML on your preferred site to extract information as you filter out content using specific words.
How to Get Help with Programming
Even if you feel confident in your abilities, you might need more coding resources to build your programming knowledge. Here are some programming exercises, quizzes, and projects that you’ll find helpful.
If you feel confident with the 10 beginner challenges listed above, then you should complete exercises designed for advanced learners. For instance, Edabit provides a series of challenges and exercises designed for students of all learning levels starting from easy to hard to expert. The site features fun coding exercises for all of the major programming languages.
Projects are arguably the best way to hone your skills and become an expert. There are sites such as FreeCodeCamp and GitHub, both of which offer open source projects for anyone to work on. Besides, once you’ve completed a project, you can list it in your portfolio to impress a potential client or hiring manager.
Programming quizzes work like normal quizzes but they focus on coding and programming languages. They are timed and the time taken for each question will vary with each website. Some sites, such as Quizizz, offer multiple-choice questions. However, quizzes focus on the theory side of coding and often don’t include a practical demonstration.
Programming Forums and Blogs
Programming forums and blogs are ideal resources if you are looking to network with other programmers in your field. Blogs are great if you are looking for personal experiences, tutorials, informative articles, or a general body of knowledge. You can use forums to post coding questions or queries that can be answered by expert programmers. Some of the best programming forums include GitHub, Stack Overflow, and CodeProject.
