Course Introduction：Implementation method: 1. Use the "+", "-", "*", "/" and "%" characters to implement addition, subtraction, multiplication, division and remainder operations; 2. Use "+=", " -=", "*=", and "/=" symbols will first perform addition, subtraction, multiplication, and division operations, and then assign the results to the variables on the left side of the operator; 3. Use the "++x" or "x++" symbols to assign variables The value of the variable is incremented (+1), and the value of the variable is decremented (-1) by using the "--x" or "x--" character.
