Run the first time and this may not be the same, from the second time after the same.

1, a[10]; Just make a label, do not allocate memory, to a[0]= (1*1)%11 when allocating memory, but in the data section of the stack to find an address assigned to a, do not initialize;
2,a? , initialization 0 is done, and the given value is assigned to the specified position in A123.
3, the highlight is a0={} of the writing, I first try to, estimate this compiler related.
