发帖数: 48 | 1 I need to let function A be an argument for function B,
but function A has two forms (override), how can I
include the two types as a general form of A in argument of B?
for example
float A(int);
float A(int, double);
I want
float B((*A)(?),other arguments)
how do I substitute content denoted by "?" | p***o

发帖数: 183 | 4 可以用function object吧
class A{
float operator()(int){...}
float operator()(int, double){...}
}
然后传一个A的实例的指针给B.
