Integers and Floating-Point Numbers in C++
The article discusses the use of integers and floating-point numbers in C++. It explains the different types of integers available in C++, including signed and unsigned integers, as well as fixed-width integer types. Additionally, it covers floating-point types and their significance for representing decimal values.
- ▪C++ supports various file extensions for source files, with .cpp and .cc being the most common.
- ▪Integers in C++ can be signed or unsigned, allowing for both negative and positive values or only non-negative values, respectively.
- ▪The standard library header <cstdint> provides fixed-width integer types, enabling precise control over the number of bits used for integer storage.

Common C++ file extensions include: .cc .cpp .cxx Enter fullscreen mode Exit fullscreen mode All three are valid for C++ source files. In practice, .cpp and .cc are probably the most common ones.
