Hello everyone,
I ahd to make a program for initializing members of a class and displaying them.The members were name , bank account no, account type and current balance.
Well , the program works well except for that null pointer assignment is displayed on the screen after correct output.Could you tell me a reason why this is happening?
Thanks,
comwizz.

void display(void)
{
