#codewithharry brother i have a problem related python programming mystr= "i live in urlabari" print(mystr.replace("i", "we")) in this code it changes all "i" in the string so how can we change only a specific word or character in python

@ashutosh-pandit 4 года назад

@@lilagadtaula7597 If you want to change :- 1). specific character then use indexing 2). Specific word then use slicing (i.e.- index range)

All the member of the base class are part of the derived class. However, the derived class can only access members that are public or protected.

@codewithharry- What was the use of pointing base class pointer to derived class object . Neither it was able to change the value of derived class variable neither it was able to display the value of derived class variable Was it just used here so that we could understand the concepts ? If yes, please reply with a yes there are many comments asking for the same Thankyou

@abrarahmad3897 Год назад

5:36 In my opinion, no error would be raised since the derived class is already inheriting the base class. Thus, it may not be wrong to point a pointer object of the base class to the derived class, Ig.

Base class ka pointer shirf base class ki Properties ko hi Access kar skta he ........ jabki derived class ka pointer dono class ki properties ko access kar skta he .....par member function ke naam same hone par derived class ka pointer phlle derived class ke function ko run call krega

@XeroGamingYT 3 года назад

5:35 error will be there I think because maybe it will also inherit the pointer to base class.

base class pointer can point to derived class object only if base class is inherited publicly to derived class. Remove Public and same will not happen.

@TheISP 3 года назад

5:36 I think there will be an error, because Base Class does not contain all features of derived class, but derived class contains all features of base class 11:30 doubt cleared, we can't access unique elements of derived class using base pointer.

@abrarahmad3897 Год назад

Harry, just a question, if we cannot access the methods and members of the derived class with the pointer of the base class then what is the use of pointing that pointer of the base class to the object of the derived class? I mean, we could simply made a base class pointer and our code would work perfectly fine while occupying less memory space.

No It Wont Throw Error Because It Is Inherited from Base Class Both Pointers Are Interchangable According to me~

@_just_random_things_ Год назад

for future me looking at this video and the random dude looking in the comments basically what it is - 1)- it is a base class pointer pointing towards the object of the derived class 2)-it can access the functions and members and functions of its own class. but by using the pointer of base class it can only access the overridden members of the derived class by making that function virtual pointers are important because they help in performance , if there is lack of functionality, in prevention od memory leak and buffer overflow

@shahmirkhan7145 Год назад

5.36 i think it can not generate error because you can inherit the base class in derived class so you can point base class object to derived class object
