Then what is it. If you do not elaborate on your question, it would be hard to help you.

Putting the bad practices aside: name was originally initialized with 5. You created multiple instances of the same class. You called input() on s2, which will display name value as your input value. Your last output on name is on s3, a newly initialized instance of the class, so name will be 5.

when code references an uninitialized value. it can print any value. i.e int x; cout << x; but it 'should' print 5 in your code. thus 'odd'

I'm sorry but the name of s3 it's not 5 on Code::Blocks

it's a very large number, I think it is a address of the memory but I can't explain it
