// I am a new C++ programmer and I have a little (??) problem with
// the operator = .
// I want to do a pointers chain . When I want to do a assignment between
// pointers , the compiler finds the = operator for the object ( I think ,
// but I am not a expert ) .
// This is the code :
#include <stdio.h>
class T
{
int t ;
T* next ;
public :
T(int) ;
~T() ; // His contenst
void print1(void);
T& operator = (T&) ;
};
T::T ( int val )
{
t = val ;
if (--val)
next = new T (val);
else
next = 0;
}
T& T::operator= (T& tt)
{
return (*this); // It's enough for this test .
}
void T::print1(void)
{
T* other = this ;
printf("\n\n");
do
printf("%d ",other->t);
while (other=other->next);
}
/****
In three lines , it gives errors :
>> Constructor : next = new T (val)
next = 0
>> print1 : other = other->sigo
He tells me to miss parameters for the constructor . The errors are
In method T::T (int):
25: bad argument list for method `operator ='
27: bad argument list for method `operator ='
In method T::print1 ():
45: bad argument list for method `operator ='
I want to do an assignment between pointer to T , not between
objects of type T .
Do I forget something important ?
Is my error a basic error ?
Thanks . A beginner .
