This article introduces the knowledge about "how many bytes the string abc occupies in memory in C language". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

The string abc occupies 4 bytes in memory, because all strings have a "\0" character as the end marker, and bytes are units of binary data, and a byte is usually 8 bits long.

Operating environment: Windows 7, DELL G3

How many bytes does the string abc occupy in memory?

The string "ABC" occupies 4 bytes in memory because all strings have a '\0' character as a terminator marker.

C is an efficient programming language that produces only a small number of machine languages and runs without any runtime environment support. Although C provides many low-level processing capabilities, it remains cross-platform in that C programs written in a standard format can be compiled on many computer platforms, including operating platforms such as embedded processors and supercomputers.

Additional information:

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

In some computer systems, four bytes represent a word, which is the unit of data that the computer can efficiently process when executing instructions. Some language descriptions require two bytes to represent a character, which is called a two-byte character set. Some processors are capable of processing two-byte or single-byte instructions. Byte is usually abbreviated as "B," while bit is usually abbreviated as lowercase "B," and the size of computer memory is usually expressed in bytes.

"C language string abc in the memory occupied by the number of bytes" on the content of the introduction here, thank you for reading.
