C++ Linker Error

[mubbashir]

I just created a program and used public inheritance. when compiling I am getting linker error of this kind.
[Linker error] undefined reference to `Person::Person(char *)'

[Linker error] undefined reference to `Person::~Person(void)'

[Linker error] undefined reference to `Student::~Student(void)'

if you declare protoypes in a header
And you want to access a method declared in the header, then you need to firstly include the header file where you want to use it(which it sounds like you have done), and secondly make sure that the implementation of MyClass is in the path that the compiler is looking in.....

This goes for constructors/destuructors as well.
That is, somewhere (for now in the directory where you are compiling) you need to define

Person::Person(char* name)
{
  /* Do somethign with name */
}
 
Person::~Person(void)
{
 /* Do Get rid of type things */
}
 
Student::~Student(void)
{
  /* Do get rid of type things */
}
