How to calculate int in c language

Overview of int type calculation rules in C language: Arithmetic operators: addition, subtraction, multiplication, division, remainder, self-increment, self-decrement Assignment operators: assignment, addition, subtraction, multiplication, division, remainder, remainder, assignment comparison operators: equal to not equal to less than greater than less than equal to greater than equal to Logical operators: logical AND logical or logical NOT Bit operators: bit AND bit or bit XOR bit left shift right shift

C language Calculation of int type

int is the basic data type representing integer in C language and occupies 4 bytes in the computer. Its calculation rules are as follows:

Arithmetic operators:

• ##Addition
• Subtraction
• Multiplication
/ Division (return real number)
• % Remainder (return the remainder of division)
• Auto-increment (increase by 1)
• -- Auto-decrement (decrease by 1)

Assignment operator:

= Assignment
• = Additive assignment
• -= Subtractive assignment
• *= Multiplicative assignment
• / = Division assignment
• %= Remainder assignment

Comparison operator:

== Equal to
• != Not equal to
• < Less than
• Greater than

<= Less than or equal to
• = Greater than or equal to

Logical operators:

&& Logical AND
• || Logical OR
• ! Logical NOT

bit operator:

& bit and
• | bit or
• ^ Bit XOR
• << Bit shift left

• Bit shift right

##Example ：

int a = 10;
int b = 5;
int c;

c = a + b; // c 为 15
c = a - b; // c 为 5
c = a * b; // c 为 50
c = a / b; // c 为 2.0（实数）
c = a % b; // c 为 0
c++; // c 为 11
c--; // c 为 10
