What is Type Promotion in C++?
Type promotion in C++ is a fundamental concept that is crucial for understanding how different data types are handled during expression evaluation. It refers to the automatic conversion of one data type to another, typically when an operation involving multiple data types is performed. This automatic conversion is performed by the compiler to ensure that the operation can be executed without any data loss or errors. In this article, we will delve into the details of type promotion in C++, its rules, and its implications in various scenarios.
Type promotion is a key feature of C++’s type system, which allows for flexibility and ease of use when working with different data types. It ensures that operations involving mixed data types are treated as if they were of a common type, making the code more readable and maintainable. In this section, we will explore the basic rules of type promotion in C++ and understand how the compiler handles different data types during expression evaluation.
