Consider the following program fragment:
for(c=1, sum=0; c <= 10; c++)
{
   scanf("%d", &x);
   if( x < 0 ) continue;
   sum += x;
}
What would be the value of sum for the input 1, -1, 2, -2, 3, -3, 4, -4, 5, -5

Consider the following code:
void main()
{
   int a[5] = {6,8,3,9,0}, i=0;
   if(i != 0)
   {
      break;
      printf("%d", a[i]);
   }
   else
      printf("%d", a[i++]);
}
What is the output of the above program?
