Accessors and Mutators C++

I am currently trying to learn C++ and following an instruction. I've researched on mutators and accessors but I need a simple explanation.
class Customer
{
public:
Customer();
~Customer();
private:
string m_name;
int m_age;
};
Right the code above is in a header file. Within the instructions it is asking me to set a public accessors and mutator for both data. How do I do this?
Also it mentions checking the age is not negative in the mutator. I know how to implement the code but I'm just confused on where to place it. Do I place the validation in this header file? or in the .cpp? or in the main method?
I know this sounds all silly and I'm sure simple but I'd like to try and understand this.

Please note that this is basic C++.
Accessor - Member function used to retrieve the data of protected members.
Mutators - Member function used to edit the data of protected members.
In your case,
class Customer
{
public:
Customer();
~Customer();
string getName(); // Accessor for the m_name variable
void editName(string in); // Mutator for the m_name variable
private:
string m_name;
int m_age;
};
Inside your .cpp file:
string Customer::getName() {
return m_name;
}
void Customer::editName(string in) {
m_name = in;
}
