What is the main difference between pointer and delegate with examples?
Fareed

Delegate to function--- is same as---- pointer to object.Delegates are function pointers.They are used when the function which needs to be called is not know at compile time.Pointers, on the other hand, are used to point to variables or object references in unsafe code. Thanx
