Operators are the foundation of any programming language. Therefore, if operators are not used, the function of C language is incomplete. Operators allow us to perform different types of operations on operands. In C, you can classify operators into the following categories: Arithmetic operatorS (+, , *, /,%, increasing after, increasing before, decreasing after, […]

There are two kinds of bit operation in C language: logical operation and logical shift operation. Logical operation C language provides four bitwise logical operators: bitwise negation, bitwise and, bitwise OR, bitwise exclusive or. At compile time, the compiler converts to different instructions based on the width of the operand. operation C language operators Assembly […]

Expression, the simplest and the most difficult. All kinds of arithmetic, logic and assignment are embedded in the same function calls. Think of them as big as the Big Dipper, moving mountains, filling seas, and withering rocks.There is a cloud of nonsense. According to yacc rules, expressions are composed of operands and operators. Operands are […]
