Sometimes, it is necessary to know and use the minimum and maximum values representable with a numeric type, such as char
, int
, or double
. Many developers are using standard C macros for this, such as CHAR_MIN
/CHAR_MAX
, INT_MIN
/INT_MAX
, or DBL_MIN
/DBL_MAX
. C++ provides a class template called numeric_limits
with specializations for every numeric type that enables you to query the minimum and maximum value of a type, but is not limited to that and offers additional constants for type properties querying, such as whether a type is signed or not, how many bits it needs for representing its values, for floating point types whether it can represent infinity, and many others. Prior to C++11, the use of numeric_limits<T>
was limited because it could not be used in places where constants were needed (examples can include the size of arrays and switch cases). Due to that, developers preferred to use the C macros throughout their code. In C++11, that...

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
