array is faster than pointer because accessing array elements
by pointers always faster.there is used one array and more pointer.we know pointer is a "value at address".
so pointers stores only address of variable but arrays are stores similar data types.

Answer / andeep singh

Pointer is faster than array if there is only one pointer used

Answer / narendra

arrays are very faster because it stores a sequential


block of memory and similar data types

pointers stores only adders of variable

but arrays are stores similar data types

Answer / s

i think pointers are faster if we talk in terms of element
addition and deletion,the priomary req..

Answer / sandeep

when compared pointers work fast ,beacause:
1.array too is pointer
eg:char s[20];
gets(s);
here we are supplying base address.
2.array notation will be inter coverted as pointers
where we can directly use pointers.

You have an int array with n elements and a structure with three int members. ie struct No { unsigned int no1; unsigned int no2; unsigned int no3; }; Point1.Lets say 1 byte in the array element is represented like this - 1st 3 bits from LSB is one number, next 2 bits are 2nd no and last 3 bits are 3rd no. Now write a function, struct No* ExtractNos(unsigned int *, int count) which extracts each byte from array and converts LSByte in the order mentioned in point1.and save it the structure no1, no2, no3. in the function struct No* ExtractNos(unsigned int *, int count), first parameter points to the base address of array and second parameter says the no of elements in the array. For example: if your array LSB is Hex F7 then result no1 = 7, no2 = 2, no3 = 7. In the same way convert all the elements from the array and save the result in array of structure.
