[Error] variable or field ‘Create’ declared void问题解决
在编写代码过程中出现bug： [Error] variable or field ‘Create’ declared void（变量或字段声明无效）
void Create( &Complex C, float x, float y) 改正：void Create( Complex &C, float x, float y)，以“&”打头的参数即为引用参数，使用方式为 ：变量类型 &具体变量
c++中[Error] cin was not declared in this scope问题解决
原因：缺少
#include<iostream>
using namespace std;
上面程序的运行结果
