In this program, You will learn how to find prime numbers in an array in c.

`Some list of prime numbers is: 2 3 5 7 11 13 17`

## Example: How to find prime numbers in an array in c.

```
#include<stdio.h>
int main() {
int arr[10], i, s, j, p;
printf("Enter size of an array:");
scanf("%d", &s);
printf("Enter array elements:");
for (i = 0; i < s; i++) {
scanf("%d", &arr[i]);
}
printf("All prime list is:");
for (i = 0; i < s; 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 size of an array:5
Enter array elements:2 3 4 5 6
All prime list is:2 3 5
```
