C program to create a new array from a given array with the elements divisible by a specific number.

Program

#include<stdio.h>
#include<conio.h>
#define MAX 50

void read_array(int a[MAX], int n)
{
    int i;
    for(i=0;i<n;i++)
    {
        printf("Element %d\t:",i+1);
        scanf("%d",&a[i]);
    }
}

void print_array(int a[MAX], int n)
{
    int i;
    for(i=0;i<n;i++)
    {
        printf("Element %d\t:%d\n",i+1,a[i]);
    }
}

void main()
{
    int arr[MAX], divi[MAX];
    int i, j, n, num, count;

    count=0;

    printf("Enter the number of elements in the array\t:");
    scanf("%d",&n);

    printf("Enter the elements of the array\n");
    read_array(arr, n);

    printf("Enter the number by which divisibility is to be checked\t:");
    scanf("%d", &num);

    j=0;
    for(i=0;i<n;i++)
    {
        if(arr[i]%num==0)
        {
            count++;
            divi[j] = arr[i];
            j++;
        }
    }

    printf("\nThere are total of %d numbers which are divisible by %d",count,num);
    printf("\nNumbers are\n");
    print_array(divi,j);
    getch();
}

Output

Enter the number of elements in the array       :8
Enter the elements of the array
Element 1       :12
Element 2       :25
Element 3       :56
Element 4       :58
Element 5       :47
Element 6       :89
Element 7       :36
Element 8       :45
Enter the number by which divisibility is to be checked :2

There are total of 4 numbers which are divisible by 2
Numbers are
Element 1       :12
Element 2       :56
Element 3       :58
Element 4       :36
