Yes, see the C99 ISO standard §6.5.2.1/2. Assuming a pointer "a" into an allocated array, a[-1] is equivalent to *(a - 1). Naturally, if (a - 1) points to an unallocated memory location, you get undefined behavior.

The following are factors of 750, meaning they go into 750 a certain number of times. To find out how many times the number goes into 750, find the corresponding number on the other side of the array. For instance to see how many times 5 goes into 750, find the 4th-last number in the array (150):1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
I recently studied a magic square. It is a square that when each row, diagonal, horizontally, or vertically is added up, it equals the same positive integer.
It cannot be part of the array.
'0' Try this: public static void main(String[] args){ } The output would be 0 even though you did not initialize any value in the int array.
Method 1: Sort the array in descending order, compare 1st and 2nd if not same , return 2nd if same return -1 Method 2: Find the largest number in the array, initialize another array with dimension 1 less than of original. Copy the array elements from the original array minus the largest element. not select largest from the second array and compare with the previous one if not same return the second largest if same return -1
