What is an Array ?

Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

 
 

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

Here is source code of the C program to copy elements of one array to another. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

 

SOURCE CODE : :

/* C program to copy elements of one array to another  */

#include <stdio.h>

int main()
{
    int first[100], second[100];
    int i, size;

    /*
     * Reads size and elements in the array from user
     */
    printf("Enter the size of the array : ");
    scanf("%d", &size);
    printf("\nEnter %d elements of first array : \n",size);
    for(i=0; i<size; i++)
    {
        printf("\nEnter %d element of first array : ",i+1);
        scanf("%d", &first[i]);
    }

    /*
     * Copies all elements from first array to second array
     */
    for(i=0; i<size; i++)
    {
        second[i] = first[i];
    }

    /*
     * Prints all elements of first array
     */
    printf("\nElements of first array are : ");
    for(i=0; i<size; i++)
    {
        printf(" %d ", first[i]);
    }

    /*
     * Prints all elements of second array
     */
    printf("\n\nElements of second array are : ");
    for(i=0; i<size; i++)
    {
        printf(" %d ", second[i]);
    }

    return 0;
}

OUTPUT : :

Enter the size of the array : 6

Enter 6 elements of first array :

Enter 1 element of first array : 1

Enter 2 element of first array : 2

Enter 3 element of first array : 3

Enter 4 element of first array : 4

Enter 5 element of first array : 5

Enter 6 element of first array : 6

Elements of first array are :  1  2  3  4  5  6

Elements of second array are :  1  2  3  4  5  6
