void setName(string x) {
name = x;
}
private:
string name;
};

int main() {
myClass myObj;
myObj.setName("John");

return 0;
}

Answer 1

you include <string> to use the string data type and its easier than using an array of chars, void is used cause theres no value to return that function is only used to give the value of x to the name variable and setName is the name of the function
