C Programming code for Printing Prime of 1D Array – KLE Tech

Write a Modular C Programming Code for Printing all Prime numbers of a 1D Array?

CODE:

#include<stdio.h>
void readArray(int[],int);
void prime(int A[],int n);
int main()
{
int n,occ,key;
int arr[100];
printf("Enter the size of Array: ");
scanf("%d",&n);
printf("Enter the elements of array: \n");
readArray(arr,n);
prime(arr,n);
}
void readArray(int arr[],int n)
{
int i;
for(i=0;i<n;i++)
{
scanf("%d",&arr[i]);
}
}
void displayArray(int arr[],int n)
{
int i;
for(i=0;i<n;i++)
{
printf("%d ",arr[i]);
}
}
void prime(int arr[],int n)
{
int i,j,p;
printf("All prime list is:");
   for (i = 0; i < n; i++)
    {
       j = 2;
       p = 1;
       while (j < arr[i]) {
           if (arr[i] % j == 0) {
               p = 0;
               break;
           }
           j++;
       }
       if (p == 1) {
           printf("%d ", arr[i]);
       }
   }

   return 0;
}

OUTPUT

Enter the size of Array: 9
Enter the elements of array:
6
5
3
2
10
9
7
5
12
All prime list is: 5 3 2 7 5
