C language is a high-efficiency programming language that only generates a small amount of machine language and can run without any operating environment support. Although the C language provides many low-level processing functions, it still maintains cross-platform characteristics. C language programs written in a standard specification can be executed on many computer platforms including operating platforms such as embedded processors and supercomputers. Compile.

Extended information:

Byte is the unit of binary data. A byte is usually 8 bits long. However, some older computer architectures use different lengths. To avoid confusion, in most international literature the word byte is used instead of byte. In most computer systems, a byte is an 8-bit unit of data. Most computers use a byte to represent a character, number, or other character. A byte can also represent a series of binary bits.

In some computer systems, 4 bytes represent a word, which is the unit of data that the computer can efficiently process when executing instructions. Some language descriptions require 2 bytes to represent a character, which is called a double-byte character set. Some processors are capable of handling double-byte or single-byte instructions. Bytes are often abbreviated as "B" and bits are often abbreviated as a lowercase "b". The size of computer memory is usually expressed in bytes.
