Difference b/w a[i] and i[a]
Is there any relation between a[i] and i[a] while using arrays..can anyone help me with this....

Bath a[i] and i[a] are same.....the variable name 'a' contains the basic address of the array.so a[i] means base address + index 'i' and also i[a] means base address + index 'i'

There is no difference in compilation perspectiveboth are internally converted as *(a+i) or *(i+a) which means the same thing

The integer size on 16 bit machine is 2 bytes.2 bytes = 16 bits.2^16 = 65536So for unsigned int range is 0 to 65536for signed int, range is -32768 to 32767And here unsigned int is used, and 40000 is within range, so it will print 40000 without any error.(Provided that the code is complete :) )

What is page thrashing?
Some operating systems (such as UNIX or Windows in enhanced mode) use virtual memory. Virtual memory is a technique for making a machine behave as if it had more memory than it really has, by using disk space to simulate RAM (random-access memory). In the 80386 and higher Intel CPU chips, and in most other modern microprocessors (such as the Motorola 68030, Sparc, and Power PC), exists a piece of...
