How to compare number with another number in an Array? [c]

I would like to know if the number the user enters is number in the array.

Here is my code:

#define ARR_SIZE 10

int main()
{
    int my_arr[10];
    int secnum = 0;
    int i = 0;

    for (i = 0; i < ARR_SIZE ; i++)
    {
        printf("Enter a number: ");
        scanf("%d",&my_arr[i]);
    }

    printf("Enter the another number");
    scanf("%d",&secnum);

    if(my_arr[i] == secnum)
    {
        printf("an ex");
    }

}

But it doesn't work.

How can I compare a number with another number in array?

Note: I don't know pointers so I need to do it without pointers.
