Operators are special symbols or keywords that perform operations. They have different types and execution orders. They mainly include arithmetic operators for mathematical operations, relational operators for comparison, and logical operators for processing booleans. Value, assignment operators are used to assign values, pointer operators are used to deal with pointers, bit operators are used to perform operations on binary bits, and conditional operators are used to select expressions based on the result of a condition.
How to use operators in C
1. What are operators?
Operators are special symbols or keywords used to perform certain calculations or operations. They can operate on variables, constants, or other expressions.
2. Operator types in C
There are various types of operators in C, including arithmetic operators, relational operators, logical operators, assignment operators, Pointer operators, bitwise operators and conditional operators.
3. Operator priority
Different operators have different priorities. Operators with higher precedence are executed first in the expression. Parentheses can be used to override the default priority.
4. Arithmetic operators
Arithmetic operators are used to perform mathematical operations such as addition (), subtraction (-), multiplication (*), division (/) and modulus Operation (%).
5. Relational operators
Relational operators are used to compare two expressions and return a Boolean value, such as equal to (==), not equal to (!=) , greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=).
6. Logical operators
Logical operators are used to operate on Boolean values, such as AND operation (&&), OR operation (||), NOT operation (!) .
7. Assignment operator
The assignment operator is used to assign a value to a variable, such as assignment (=), addition assignment (=), subtraction assignment (-= ), multiplicative assignment (*=), division assignment (/=) and modulo assignment (%=).
8. Pointer operators
Pointer operators are used to process pointers to other variables or objects, such as address operator (&) and dereference operator (*) , addition operator ( ), subtraction operator (--).
9. Bit operators
Bit operators are used to perform operations on binary bits, such as AND operation (&), OR operation (|), XOR operation (^) , left shift operator (<<), right shift operator (>>).
10. Conditional operator
The conditional operator is used to select an expression based on the conditional result. The syntax is:
<code>(condition) ? true-expression : false-expression</code>
