Answer / manish
array is a similar type of data but structure are collection of any type of data
array alway start with 0
e.g.a[5]
in this array 6 element
structure has no diffination
it is a collection of n num any data type

array:arrray is a collection of similar datatypes stored in
common name.it is a scpe of variable
structure:structure is a dissimilar datatypes stord in
common name.it is a scope of datatype

Answer / triveni
ARRAY:- array includes same type of data types.
we dont use any keyword while defining array.
array always passed/called by reference to function.
we cant copy one array to another even though both arrays
ae of same type.
it is fixed in size.
structure:-array includes same or differnt data type
elements .
we use struct keyword while definings structure.
by default structure passed/called by value to function.
we cant copy one structure to another if both are of same
struct type and having different variabe names.
it is not fixed in size.

Array is the collection of homogeneous data elements
whereas Structure is the collection of heterogeneous
data types elements.

Answer / priya
Array have same data type and static memory allocation....
Structure have different data type and dynamic memory
allocation

Answer / bilal wazir
arrays are the group of related data types but structure are
the different data items
| Is This Answer Correct ? | 2 Yes | 0 No |
ARRAY:
An array is defined as a group of related data items stored by means of a single variable name.
STRUCTURE:
Structure is defined as a data type to represent several different types of data with a single name.
DIFFERENCE BETWEEN ARRAYS AND STRUCTURES:
1.All data in a array should be of same data type.But in structures data can be of different data types.
2.Individual entries in an array are called elements.But in structure individual entries are called members.

Answer / rkv charan
Array:
1.static memory allocation.
2.array size is fixed.
3.array can't have bit fields.
structure:
1.Dynamic memory allocation.
2.structure size is changed dynamically.
3.structure can contain bit fields.

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.
