ARRAYS

Single – Dimensional Arrays

l Array is a collection of variables of the same data type that is referenced by a common name.

l 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();

}

Parts of the array are:

Array[0] = 25

· Array name - Array

· Subscript or index - [0]

· Array element - 25

Array declaration

l 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.

size defines how many elements the array will hold.

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

int number[100] , answer [25];

Array Initialization

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

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