S1 = S1 + 1; this statement is incorrect. S1 is of the short type, which occupies 2 bytes. S1 + 1 is automatically converted to the int type, which occupies 4 bytes, if the short type variable S1 is assigned, the precision of two bytes is lost, which is not allowed. If you want to do this, you can write as follows:
S1 = (short) (S1 + 1 );
Short S1 =

Train of thought: Since 1+1 is set up in a very large range of data, we might as well split two primes and divide the remaining numbers into two primes.

Speaking of this formula, is actually a classic question, recently saw a video said to draw a conclusion: the answer is 0.5, I think it is very interesting, when we go to school, we all calculate:
