WebC++ 中有四种类型转换：静态转换、动态转换、常量转换和重新解释转换。 静态转换（Static Cast） 静态转换是将一种数据类型的值强制转换为另一种数据类型的值。 静态转换通常用于比较类型相似的对象之间的转换，例如将 int 类型转换为 float 类型。 静态转换不进行任何运行时类型检查，因此可能会导致运行时错误。 实例 int i = 10; float f = … Web左值和右值的概念早在C++98的时候就已经出现了，从最简单的字面理解，无非是表达式等号左边的值为左值，而表达式右边的值为右值，比如： int x = 1; int y = 3; int z = x + y; 但是还是过于简单，有些情况下是无法准确区分左值和右值的，比如： int a = 1; int b = a; Web1.3 函数重载调用准则. 函数重载调用时，先去找名称相同的函数，然后进行参数个数和类型的匹配。. 找不到匹配的函数就会编译失败，找到两个匹配的函数也会编译失败；. 重载 … chiq shoes
