— Why not

Why in c++ when i have a char[10] in a class for example in constructor i should initialize the char[10] because is autogeneraed?

— You shall initizialize variables before you use them otherwise the value might be indeterminate

— Yeah but no errors everything works when the constructor without parameters is called

— In case of doubt whenever you intitialized everything before use, valgrind is your friend

— Can you provide an example?

— You will not run into problems with 25 lines of codes, but if you have 25k line of code, uninitialized memory you expect to be initialized will hurt you back
