Array Address
Is it possible to change the address of an array?
kamal7725
- Nov 30th, 2007
No, not all. And i don't see any condition in which i need to change the address of the array.This is because if we allow to change the address of the array, there is no way get that memory address again, and memory leak would be there.

We can not change array address.if you try to change the address of array the compipler gives an error-"l value is required"

Why C?
Why C considered as a High Level language? In C we are using pointers to access memory ,hence why HLL?
asif.aaag

because C is very simple to learn, easy to use and its reliable thats y most of them opt for C.And C is base for every language you learn...That is C++ and java's foundation is C...It is like a foundation of a building over which other floors are built

Create a prototype based on client requirement to get better understanding and to iorn out the differences bettween client and ours. Once everyone on the same page, start working on implementing these into design and development.
