In short it is because of strict type checking in Java. In Java conditional statement expects only boolean inside them and as x-- can be any integer which will not be boolean that is why it is not allowed in Java.

Correct usage would be while(x-- > 0) instead while(x--)

While compiling step by step if we don't include -o while generating 1.i it will not create a new file and write the output on stdout, but in case of generating 1.s/1.o if we don't write -o it is automatically creates a new file and writes data into it. Why?
