Question
I'm getting this error message with the code below:
class Money {
public:
Money(float amount, int moneyType);
string asString(bool shortVersion=true);
private:
float amount;
int moneyType;
};
First I thought that default parameters are not allowed as a first parameter in C++ but it is allowed.
Solution
You are probably redefining the default parameter in the implementation of the function. It should only be defined in the function declaration.
//bad (this won't compile)
string Money::asString(bool shortVersion=true){
}
//good (The default parameter is commented out, but you can remove it totally)
string Money::asString(bool shortVersion /*=true*/){
}
//also fine, but maybe less clear as the commented out default parameter is removed
string Money::asString(bool shortVersion){
}
