C++ 未正确调用运算符溢出函数调用
所以,我得到一个错误,在VS 2012中的错误C4930,说C++ 未正确调用运算符溢出函数调用,c++,compiler-errors,lnk2001,C++,Compiler Errors,Lnk2001,所以,我得到一个错误,在VS 2012中的错误C4930,说 prototyped function not called (was a variable definition intended?) 基本上,由于某些原因,我使用运算符溢出函数进行的所有函数调用都没有被正确调用。我见过一些人这样写函数调用 Comp_Num Comp_Num::operator- (Comp_Num &c1, Comp_Num &c2); 当我添加Comp_Num::VS下划线操作符中的文本编辑
prototyped function not called (was a variable definition intended?)
基本上,由于某些原因,我使用运算符溢出函数进行的所有函数调用都没有被正确调用。我见过一些人这样写函数调用
Comp_Num Comp_Num::operator- (Comp_Num &c1, Comp_Num &c2);
当我添加Comp_Num::VS下划线操作符中的文本编辑器时,会出现红色的波形
我也得到3链接2001错误。我为双r1\u final和r2\u final所做的变量声明有问题。我认为他们没有在函数调用之外初始化变量。这总共是一条错误消息

这是密码。我要说的部分是operation()函数的底部。提前谢谢

if(operate == "addition")
cm = c1 + c2;
else if (operate == "subtraction")
cm = c1 - c2;
else if (operate == "multiplication")

以下是问题所在:
if(operate == "addition")
Comp_Num operator+ (Comp_Num &c1, Comp_Num &c2);
else if (operate == "subtraction")
Comp_Num operator- (Comp_Num &c1, Comp_Num &c2);
else if (operate == "multiplication")
Comp_Num operator* (Comp_Num &c1, Comp_Num &c2);
如果要使用运算符,只需将它们用作运算符即可
Comp_num c1, c2, c3; // get these from somewhere.
if(operate == "addition")
c3 = c1 + c2;
else if (operate == "subtraction")
c3 = c1 - c2;
else if (operate == "multiplication")
c3 = c1 * c2;
另一个错误是因为您需要在类之外定义静态变量。您也可以在此时初始化它们。请在类定义下面尝试类似的操作:
double Comp_Num::r1_final = 0;
