What are the characteristics of operators in Go language?

Go language is a compiled, highly concurrency-friendly, development-friendly language, and its operators are an important part of this language. This article will mainly explore the characteristics of operators in the Go language.

Go language operators are mainly divided into five types: arithmetic operators, relational operators, logical operators, bitwise operators and assignment operators. Their characteristics are introduced below:

1. Arithmetic operators

The arithmetic operators in Go language are similar to those in other languages, including addition, subtraction, multiplication, division, and modulus. Unlike other languages, the division operator / in the Go language returns an integer result instead of a floating point number when used by integer divisors and divisors.

In addition, there are unary operators and - in Go language, which are used to represent positive or negative numbers.

2. Relational operators

The relational operators in Go language are used to compare whether two values ​​are equal or have a relationship of magnitude. The more special ones are the == and != operators, which can be used to compare all basic types, arrays, structures, pointers, etc., but cannot be used to compare function types.

3. Logical operators

The logical operators in Go language include &&, || and ! , respectively represents logical AND, logical OR and logical negation. Similar to other languages, in logical operations, True and False are represented as 1 and 0 respectively.

4. Bitwise operators

The bitwise operators in Go language include bitwise AND&, bitwise OR| , bitwise XOR^ and bit shift operations and <code>>>. Bitwise operators are different from logical operators in that they operate based on binary bits.

5. Assignment operators

The assignment operators in Go language include basic assignment operators = and compound assignment operators, such as =, -=, *=, /=, etc. Similar to other languages, the compound assignment operator first calculates the value on the right side of the equal sign, and then assigns the calculation result to the variable on the left side of the equal sign.

In general, the characteristics of operators in Go language are:

1. The basic operators are similar to other languages, but there are some subtle differences;
2. Language The operator types in are relatively comprehensive;
3. Except for arithmetic operators, other operators operate based on binary bits;
4. The assignment operator supports compound operators and basic operators.

In general, operators are a very important part of programming languages. Mastering the characteristics and usage of operators can improve the efficiency and readability of the code.
