[問題] overloading ^
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
c++
問題(Question)：
overloading ^
我有一個物件 A , 我要overloading ^ ,使得 A^3是合法的.
但弄不出來, 我試了以下兩個寫法:
1. A A::operator^(float &x){
A temp;
temp.variable = pow(variable , x);
return temp;
}
2. friend A operator^(const A &t, float &x){
A temp;
temp.variable = pow(t.variable, x);
return temp;
}
這樣呼叫 A^3
都會說"no match for 'operator^' in ..... "
請問是錯在哪? 感謝
