You are given a sequence of integers as input, terminated by a -1. (That is, the input integers may be positive, negative or 0.

Question

if(y>z)
{
x=z;
z=y;
y=x;
break;
}
break;

}
for(;;)
{
scanf("%d",&x);
if(x==-1)
break;
if(x>z)
{
y=z;
z=x;
continue;
}
if(x>y)
{
if(x==z)
{
continue;

}

Sorry, I don't quite understand your question. Please be more specific to what you are asking.

Answer 2

If you've written this as a means of helping someone out in the future, it would be better to post it as a code in the codes section, not the questions section.
