I’m trying to alternate array elements high to low sequence.It’s half working correctly and then work normally(low to high).I can’t figure out the problem,Can you please help me?  
My code:

```auto
#include <stdio.h>

int main()
{
    int ara[] = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100};
    int i, j, temp;

    for(i = 0,j = 9; i < 10; i++,j--){
        temp = ara[j];
        ara[j] = ara[i];
        ara[i] = temp;
    }

    for(i = 0; i < 10; i++){
        printf("%d\n", ara[i]);
    }
    return 0;
}

```

My output:

```auto
100
90
80
70
60
60
70
80
90
100

Process returned 0 (0x0) execution time : 0.016 s
Press any key to continue.

```

Expected Output should be like:

```auto
100
90
80
70
60
50
40
30
20
10

Process returned 0 (0x0) execution time : 0.016 s
Press any key to continue.

```
