Don't understand c++ error about overloaded functions [on hold]

I have a student struct:
struct Student {
std::string name;
int age;
double finalGrade;
std::string toString() {
return "Name: " + name + "nAge: " + std::to_string(age) + "nFinal Grade: " + std::to_string(finalGrade);
}
};
And I want to write my own comparison function to use with the sort() method.
bool compareByName(const Student &a, const Student &b) {
return (a.name).compare(b.name) > 0;
}
I'm getting an 'overloaded function differs only by return type from 'void compareByName(const Student &,const Student &)' error.

You seem to have another method elsewhere with the signaturevoid compareByName(const Student &,const Student &), which only differs from the other version by its return type, which isn't allowed. Do you need the other version? It seems odd for a comparing function to have a void return type.

@Carcigenicate I had a void return type in my function declaration.. Thanks for pointing me in the right direction

Strange you would discover the error now, since the error message you posted is stating exactly what @Carcigenicate pointed out.

@whelanevan6 -- often the deluge of error messages and notes that you get when you mess up a template contains exactly the information you need to find the problem. You have to wade through it, but for this example, I'm guessing that somewhere shortly after the error message itself there were a couple of notes that showed where this function was defined and where the conflicting one was declared. Everything from the first "error" message to the next "error" message is discussion about what the first error message means.
