Bounds Checking

In 'C' there is no check to see if the subscript used for an array exceeds the size of the array. Data entered with a subscript exceeding the array size will simply be placed in memory outside the array. This will lead to unpredictable results and there will be no error message to warn you that you are going beyond the array size.

main()

{

                int num [40],i;

                for(i=0; i<=50; i++)

                {

                                num[i] = i;

                }

}
