问题
I noticed once that when I declare an array,
int arr[10];
after a while the value of array member changes although nothing affects it during a period. Then I made use of dynamic allocation with "new" and the problem solved. I thought that everything should be declared dynamically. But this shouldnt be true. What may be a logical reason?

Could be number of reasons:
- Initialize your array member if it is on local storage or it contains any random value if you didn't.
- You probably overwrite the bounds of some other array in the same function which corrupts the stack and your array.
- You corrupt the stack in some magical way.
