To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as foll

, the_number is set to 4. After setting the parameters, we enter the function body. Because 4 is less than 10, the_number is changed to "04", and the the_number value is returned using the return command. After "04" is returned by fixNumber, in this example, fixed_minute is equal to "04 ". We will study this process step by step. Assume that the time is 12:04:05. We start with the announceTime () function.
