void main()

{unsigned length x;

scanf("%ul "，& ampx)；

int y；

if(x & gt； 1。 & ampx & lt 100000)y = 3；

else y = 4；

printf("y=%d\n "，y)； }

That's it. That's it.

note:

1 & lt； X< 100000 means:

Compare 1 with x first, if 1

Then compare the true and false values with 100000.

Some compilers prompt for type conversion.

Pay attention to the correct usage: x> 1. & ampx & lt 100000

Equivalent to (x>1); & amp(x & lt 100000)
