C++错误之一 :invalid initialization of non-const reference of type ‘xxx&’ from an rvalue of type ‘xxx’ 1、看代码 2、编译结果 3、分析和解决 就拿f(a + b)来说,a+b的值会存在一个临时变量中,当把这个临时变量传给f时,由于f的声明中,参数是int&,不是常量引用,因为c++编译器的一个关于语义...
在调用函数的时候传递的是int类型的数据，但那个函数定义的参数类型不是int（比如是结构或者指针或者数组）。include include"stdlib.h"int main(){ int i,j,k;int *q;q=(int*)malloc(sizeof(int));scanf("%d %d %d",&i,&j,&k);if(i>j){ if(i>k)q=i;else q=k;} else q=&j;...

I have a class containing a map member that I want to initialize at declaration time. I know I can do it in the cpp file but I'm having a problem with the order of initialization (static initialization order fiasco). My questions are: Is it possible that the scenario in which, the T...
