What does & mean in C language? The

& symbol has two meanings in C language. One represents the address operator, which is a unary operator. Its function is to obtain the memory address of a variable; while the other represents It is a bitwise operator and a binary operator. Its function is to AND the corresponding binary bits of two numbers.

C language operators

Arithmetic operators

are used for various numerical operations. There are seven types including addition ( ), subtraction (-), multiplication (*), division (/), remainder (or modular operation, %), autoincrement ( ), and autodecrement (--).

Relational operators

are used for comparison operations. It includes six types: greater than (>), less than (<), equal to (==), greater than or equal to (>=), less than or equal to (<=), and not equal to (!=).

Logical operators

are used for logical operations. Including and (&&), or (||), not (!).

Bit operation operator

The quantities involved in the operation are operated in binary bits. It includes six types: bitwise AND (&), bitwise OR (|), bitwise NOT (~), bitwise XOR (^), left shift (<<), and right shift (>>).

Assignment operator

is used for assignment operations, which are divided into simple assignment (=), compound arithmetic assignment (=,-=,*=,/=,%=) and compound bit operations There are eleven types of assignments (&=,|=,^=,>>=,<<=) in three categories.

Conditional operator

This is a ternary operator used for conditional evaluation (?:).

Comma operator

is used to combine several expressions into one expression (,).

Pointer operator

is used for two operations: content (*) and address (&).

The byte count operator

is used to calculate the number of bytes occupied by the data type (sizeof).

Special operators

include brackets (), subscripts [], members (→,.), etc.
