1. 什么是表达式? C语言中的表达式一种有值的语法结构,它由运算符将变量、常量、函数调用返回值结合而成。 1.1 变量 变量名本身是一个表达式,表达式的值是变量当前的值。复杂的表达式由[],->,., 和单目运算符*构成。 1.2 常量 常量名本身是一个表达式,字面常量也是表达式。对于这两者,表达式的值是常量当前的...

1)基础概念 C++定义了一元运算符(unary operator)和二元运算符(binary operator),作用于一个运算对象的运算符是二元运算符,如取地址符( & )和解引用符( * );作用于两个运算对象的运算符是二元运算符,如相等运算符( == )和乘法运算符( * )。除此之外,还有一个作用于三个运算对象的三元运算符(Ternary Oper...
