Error in constructor - C++ -

i have learnt object oriented programming concepts in python, want transfer knowledge c++, , have trouble basic implementation used easy using python.

#include<iostream> using namespace std;  class animal{      char name;     int age;      public:     animal(char name, int age); };  animal::animal(char name, int age) {     this->name = name;     this->age = age; }  int main() {     animal dog ("megg", 10);      cout << "name: " dog.name <<endl;      return 0; } 

when compile code, lot of messages, such as:

error: no matching function call  'animal::animal(const char[5], int)' note: animal::animal(char, int) <near match> note: candidate expects 1 argument, 2 provided 

thanks!

you don't need this->name = name in constructor definition

"megg" string literal. can cast "megg" const char * not char (this causing error).

or better yet. can use c++ standard library string class std::string

#include <iostream> #include <string>  class animal{      std::string name;     int age;      public:     animal(std::string name, int age);     std::string getname() const;     int getage() const; };  animal::animal(std::string name, int age) {     name = name;     age = age; }  std::string animal::getname() const {   return name; }  int animal::getage() const {    return age; }  int main() {     animal dog ("megg", 10);      std::cout << "name: " << dog.getname() << std::endl; // error in line. missing << between "name: " , dog.name      return 0; } 

some additional edits:

you should avoid using using namespace std takes in standard library (from files you've included) , puts in global namespace. can instead use scope resolution operator :: seen above.

when start working multiple libraries may encounter both have class named vector or string, or functions same name. way avoid specify namespace want use.

or alteratively can following:

using std::cout; using std::endl; using std::string; 

additionaly in order program work need way access object's member variables. making variables public or better practice add accessor functions.
