ARRAY IN C

Array In C

In C, array is a collection of variables that are stored in a continuous memory of same data type.

It can be accessed by common name and index number.

Syntax:

data_type array_name[array_size];

Example:

int myArray[9];

Types of array in C:

There are two main types of array used in C programming language:

1. One-dimensional array
2. Multi-dimensional array

One-dimensional array:

• One dimensional array is also called as single dimensional array.
• It is a collection of same data type elements which are stored in a continuous memory location.
• An array's index, which starts at 0 and goes up to the array's size minus 1, is used to access its elements.

Program:

#include <stdio.h>
int main()
{
int arr[8] = {1, 2, 3, 4, 5,6,7,8};
int i;
printf(" values: ");
for (i = 0; i < 8; i++)
{
printf("%d ", arr[i]);
}
printf("\n");
return
0;
}

Output:

Values: 1 2 3 4 5 6 7 8

Multi-dimensional array:

• An array with more than one dimension is referred to as a multi-dimensional array.
• It is a collection of array,the two dimensional array is the most basic multi-dimensional array.

Program:

#include <stdio.h>

int main()

{

int arr[3][4] = {{11, 12, 13, 14}, {15, 16, 17, 18}, {19, 20, 21, 22}};

for (int i = 0; i < 3; i++)

{

 for (int j = 0; j < 4; j++) 

{

 printf("%d ", arr[i][j]);

 }

 printf("\n");

 }

return 0;

}

Output:

11 12 13 14

15 16 17 18

19 20 21 22
