C语言算术运算符是哪些？

1. 模块运算“%”和“Module”是“mod”的音译，常用于编程中。Mod表示补足。模运算在数论和程序设计中有着广泛的应用，从奇偶数到素数，从模幂运算到最大公约数，从孙子问题到凯撒密码问题，都充满了模运算。C语言使用“%”表示模块化操作，如7%2=1、8%5=3等

2。Autoincrement操作“C语言用”表示Autoincrement操作，分为前缀Autoincrement和后缀Autoincrement，其效果是自身变量值1。如果前缀本身增加，例如“a=5B=a”，则运行结果为“a=6，B=6”。如果后缀自动增加，例如“a=5B=a”，则运行结果为“a=6，B=5”。

3. 自减法运算--“C语言用”--“表示自减法运算，分为前缀自减法和后缀自减法，其效果是自变量值-1。如果前缀本身减少，例如“a=5B=--a”，则运行结果为“a=4，B=4”。例如，“a=5B=a--”，运行结果为“a=4，B=5”。扩展数据：C语言常用运算符：加法-：减法>：位右移：大于>=：大于或等于=：加法赋值运算-=：减法赋值运算*=：乘法赋值运算/=：除法赋值运算%=：模赋值运算

逻辑非，logical and，logical or

在上述三个逻辑运算符中，logical not的优先级最高，logical and次之，logical or的优先级最低。换句话说，算术、逻辑和赋值运算符的优先级顺序是：逻辑非算术>逻辑与、逻辑或|>赋值

c语言中什么符号的运算级别最低？

int main（）]{

int a，b

char ch

printf（“please enter x=”）

scanf（%d，&A）

printf（“please enter y=”）

scanf（%d”，&B）

printf（“please enter the required operation:”）

scanf（%C“，&ch）

switch（CH）

case“结果，这就是[printf（X-Y as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为作为和[0
