Learnings of the Week (CAMAY)

We had a lesson this week but we weren't able to discuss it.

It's all about ARRAYS. Array is a collection of variables of the same data type that is referenced by a common name.

EXAMPLE:

#include
main()
{
int array[4]={25,5,7,11,163};
clrscr();
printf(“%d %d %d %d %d”, array[0], array[1], array[2],array[3],array[4]);
getch();
}

THE OUTPUT FOR THE EXAMPLE IS:

25 5 7 11 163


PARTS OF ARRAY

Array[0] = 25

"Array" is called the array name.
"[0]" is the subscript or index.
"25" is the array element.


* The general form for any declaration is as follows:

type array_name[size]

~> where:
---> type is any valid data type in Turbo C which declares the type of values that array will hold.

---> array_name is a valid variable name which will name the array. It defines how many elements the array will hold.


* The two declarations for arrays number and answer can be combined into a single declaration:

int number[100] , answer [25]


Arrays can give initial values during the declaration. This is called array initialization..

int Array1[5]={25, 5, 7, 11, 163}
