If the constructor is defined explicitly then, the compiler will not define the constructor implicitly
is it true ???
is it also true for copy assignment operator and copy constructor operator, that if we create copy assignment operator or copy constructor operator, the copiler will not define the default one
and if we define different copy assignment or contructor operator and tend to use the default one, will it give error
please answer all questions seperately, i am very confused …
yes this is true
you can test it by creating class and constructor
look at this code
this is how we use copy constructor
what is your doubt in this ??
plz explain your 2nd doubt
yaah !! i got most of the second doubt but clear me last
for constructor if we make our own constructor than complier will not make the default one . but the default copy assignment and copy constructor should be there na irrespective of whether the constructor is defined or not ??
Yes
If we don’t define our own copy constructor, the C++ compiler creates a default copy constructor for each class which does a member-wise copy between objects. The compiler created copy constructor works fine in general. We need to define our own copy constructor only if an object has pointers or any runtime allocation
