CODE
        for (m=0; m<7; m++)
        
            if (best_schedule[m] < check)  
            {
                                                                check=best_schedule[m];      
                best_schedule[m]=p;    
            }
        
        printf("%d , %d, %d, %d, %d, %d",best_schedule[0],best_schedule[1],best_schedule[2],best_schedule[3],best_schedule[4],best_schedule[5],best_schedule[6]);
        getchar();


By the former I give a price to the first availiable place in an array. What I want to do is to give price to the last availiable place of the array. I thought that I could do that by for ( m=6; m>-1; m--); but it doesn't seem to work. Any ideas?

Thanks

As you loop through the array, test each one to see if it is available. If you mean empty spot, just check to see if it is NULL. If they have values, check the value to see if it should be replaced with the new value of P. Once you have found the spot to place it, you can break the loop using the break statement.

I hope that makes sense to you. Enjoy! smile.gif

How could I do the opposite? Put the price in the last null space of the array?

Start your looping to run from the bottom (start your for loop instead of zero as the index of the last spot in the array, check to see if i >= 0 and decrement i instead of incrementing it).

cpp

// if array was 10 slots (index 0 - 9)...

// Run through the loop backwards
for (int i = 9; i >= 0; i--) {
     //do checks
}
