Modern C++: Efficient and Scalable Application Development

By: Richard Grimes, Marius Bancila

Overview of this book

C++ is one of the most widely used programming languages. It is fast, flexible, and used to solve many programming problems. This Learning Path gives you an in-depth and hands-on experience of working with C++, using the latest recipes and understanding most recent developments. You will explore C++ programming constructs by learning about language structures, functions, and classes, which will help you identify the execution flow through code. You will also understand the importance of the C++ standard library as well as memory allocation for writing better and faster programs. Modern C++: Efficient and Scalable Application Development deals with the challenges faced with advanced C++ programming. You will work through advanced topics such as multithreading, networking, concurrency, lambda expressions, and many more recipes. By the end of this Learning Path, you will have all the skills to become a master C++ programmer. This Learning Path includes content from the following Packt products: • Beginning C++ Programming by Richard Grimes • Modern C++ Programming Cookbook by Marius Bancila • The Modern C++ Challenge by Marius Bancila

Problems


Here are the problem-solving sections for this chapter.

23. Binary to string conversion

Write a function that, given a range of 8-bit integers (such as an array or vector), returns a string that contains a hexadecimal representation of the input data. The function should be able to produce both uppercase and lowercase content. Here are some input and output examples:

Input: { 0xBA, 0xAD, 0xF0, 0x0D }, output: "BAADF00D" or "baadf00d" Input: { 1,2,3,4,5,6 }, output: "010203040506"

24. String to binary conversion

Write a function that, given a string containing hexadecimal digits as the input argument, returns a vector of 8-bit integers that represent the numerical deserialization of the string content. The following are examples:

Input: "BAADF00D" or "baadF00D", output: {0xBA, 0xAD, 0xF0, 0x0D} Input "010203040506", output: {1, 2, 3, 4, 5, 6}

25. Capitalizing an article title

Write a function that transforms an input text into a capitalized version, where every word starts with an uppercase...
