Answer / guest

Arrays automatically allocate space which is fixed in size and
location; pointers are dynamic.

Answer / santosh

array is refered directly to the elements.
but in pointers we refers to address of the elements but not
elements . indirect calling of the elements.

Answer / pravinash

array is collection of similar datatype. it is a static
memory allocation means we can not increment and decrement
the arry size once we allocated. and we can not increment
the base address, reassign address.

pointer is a dynamic memory allocation. we can allocate the
size as we want, assigning into another variable and base
address incrementation is allowed.

Answer / jaroosh

Arrays are simply pointers THAT CANNOT be reassigned, ie,
constant pointers to some memory locations. They do not
"magically preserve" any information about array size or
whatever that some suggest, they are just a type of constant
pointers, nothing more.
For example , the following :
int a[] = {1,23};
a++;
will throw a compiler error, something like : a is not an
Lvalue, which means that you cannot assign or change the
value of a.

Answer / pushpanjali panda

Arrays automatically allocate space, but can't be relocated
or resized. Pointers must be explicitly assigned to point
to allocated space (perhaps using malloc), but can be
reassigned (i.e. pointed at different objects) at will, and
have many other uses besides serving as the base of blocks
of memory.

Answer / siddhartha

Arrays allocate the memory space which cannot resized or
reassigned. But in case of pointers the memory size can be
resized

Answer / tapan

Array is slow compare to pointer

Answer / swetha.j.n

Array is a group of elements.But pointer is not a group of
elements.
Array refer to the data in memory location.But pointer
refer to the address in memory location.

Answer / rag

ARRAYS are allocated at compile time.
POINTERS are alocated at run time.
USE POINTERS FOR PROGRAM EFFICIENCY,BECAUSE MEMORY IS
PRECIOUS ONE. So to reduce memory use pointers.

Answer / sankar s

array refer data in memory location , pointer refer address
to the memory location ,pointer refer the pointee
int *a;
int b[10];
a=&b;
where a is the pointer array b is pointee which point out
the starting memory location of an array.

Blade logic interview question. 1st round is a written tests with 15 multiple questions from c and c++. All are simple basic question. Like int main () { Int i=65; Return printf(“%c”, i); } 2nd and 3rd round is technical interview. The position for which I was interview was core UNIX and c. Yes it is for system programming. The company has product name blade server. For their server they are creating their own command for their purpose. Example cd command. We can implement it in a c program by using the chdir() function. So the question asks related to PID, fork, pipe, shared memory, signal. Write a program in c which will act as cp command.
