WA in GLJIVE

[calmhandtitan]

after trying all the possible cases for problem http://www.spoj.com/problems/GLJIVE/ given on coci(searched google 'coci gljive' and downloaded the first pdf)
m still getting WA

here's my code

[bbone=C,543]

include "stdio.h"

int main()
{

	int a[10], i,sum = 0, max, min;

	for ( i = 0; i < 10; ++i)
		scanf("%d",&a[i]);

	for (i = 0; i < 10; ++i)
	{
		sum = sum + a[i];
		if(sum > 100)
			break;
	}

	max = sum;
	min = sum - a[i];

	max = max - 100;
	min = 100 - min;

	if(min<max)
		printf("%d\n",100-min );
	else
		printf("%d\n",100+max );	
return 0;

}

please help me figure out the bugg

What is the value at a[10]?

[fedelebron]

You are saying min = sum - a[i] outside of the loop. After your second loop ends, it's condition, i < 10, is not true, so i = 10. So that line accesses a[10]. There is no a[10]. Valid indices for a are 0, ..., 9. Your program invokes undefined behavior.

It's also , not "stdio.h".

In general, if you are only going to need i inside the loop, in C++ and C99 you can say "for (int i = ... )", and the compiler will alert you if you are using i outside of the loop, because it won't be defined.

question says that if total points reaches exact 100 then stop else if select closer val.
