How to solve it
George Pólya
A classic guide to breaking problems into parts and testing strategies, the same habit Spraul builds through his exercises. Its heuristics apply well beyond mathematics, as the source book also argues.

★★★★★5.0 (1)
A beginner's programming book that teaches how to approach problems, not just which syntax to type, using open-ended exercises that reward slow, deliberate thinking.
What It's About
Think Like a Programmer is an introductory programming book that treats problem solving as its main subject and uses C++ as the vehicle. Spraul is less interested in where the semicolons go than in showing how a programmer moves from a vague goal to a working plan. Most chapters take a single concept, such as loops, functions, classes, pointers, or recursion, and use it to illustrate a way of approaching problems rather than just a feature of the language.
The reading experience is closer to a workshop than a reference book. The exercises are open-ended, so there is often no single right answer, and working through them is where most of the learning happens. You will be asked to break a problem into parts, choose a data structure, and weigh tradeoffs. Expect to get stuck and then find your own way out, because the book trusts you to do that work.
Because the examples are in C++, you meet pointers and dynamic memory directly rather than having them hidden behind higher-level abstractions. The emphasis on method, such as splitting problems up and organizing your thinking before writing code, carries over to any language. It reads as a patient, practical companion for someone who has tried a language or two and wants to understand why code is shaped the way it is.
Read this if you…
- want to learn programming but feel stuck on how to start solving a problem
- enjoy open-ended exercises and don't mind working slowly through hard questions
- want a foundation whose lessons still apply after you move on from C++
Skip it if you…
- want a quick language reference or a fast route to building a specific app
- are looking for a current guide to modern C++ features and idioms
Key Ideas
- 1
Problem solving is a skill separate from syntax
The book's central claim is that knowing a language's rules is only part of programming. The harder part is turning a fuzzy goal into a sequence of steps a machine can follow. Spraul treats that translation as a learnable skill, and each chapter asks you to practice it rather than simply memorize the feature under discussion.
- 2
Decomposing problems before writing code
A large problem becomes manageable when you split it into discrete pieces that can be solved and tested separately. The book repeatedly models this habit, showing how to name the parts, decide what each one must accept and return, and only then fill in details. The approach works as well on paper or in your head as it does at a keyboard.

Choosing the right data structure for the job
Many programming difficulties are really difficulties of representation. The same task can be easy or painful depending on how the data is stored. The book encourages you to ask what operations you need most often and to pick a structure that makes those operations natural, rather than defaulting to whatever you saw first.

Recursion and dynamic memory as thinking tools
Recursion and manual memory management are often taught as hurdles to be cleared. Here they are presented as ways of structuring a solution. Recursion shows how a problem can be defined in terms of smaller versions of itself, and dynamic memory shows how a program can decide at runtime how much space it needs.
Limitations
The book predates recent C++ standards, so modern language features and idioms are largely absent, and some code style will look dated to working developers. Readers who want a steady supply of worked answers may find the open-ended exercises frustrating, since the book prioritizes your own reasoning over complete solutions. It does not cover web development, frameworks, or professional tooling, and its treatment of algorithms is a starting point rather than an in-depth survey.
Questions Readers Ask
- Do I need to know C++ before reading Think Like a Programmer?
- No. The book is written for people new to programming and introduces its C++ material gradually, one concept per chapter. The language is mainly a vehicle for the problem-solving ideas. If you have never written code, expect the early chapters to be approachable but the exercises to take real effort.
- Is it still worth reading given its age?
- Yes, for the problem-solving method, which does not depend on any version of the language. The specific C++ conventions and tooling are dated, so pair the book with a current language guide if you plan to write production code. The habits it teaches, such as decomposing problems and choosing data structures deliberately, remain useful.
