'* How to solve a vector related C++ program with Process returned -1073741819 (0xC0000005) *
[enter image description here][1]
As I am trying to code a program for ATM SYSTEM ,I am facing a problem with the Pin_change function in the second Derived class Access when I call this funtion from Main() method.
Please Help me here to, How to solve the mistake of Process returned -1073741819 (0xC0000005) at the call of Pin_change () from Main() Method ?? It terminates their automatically.. I will Solve it again with your best Suggestion.
