Question

我似乎无法计算此代码中的常规工资。它只是计算加班时间而不是包括定期工资在内的全部工资。 Here是OAMulator编译器的链接。

SET 40     #put the value 40 into the accumulator
STA 50    #store the value 40 in address 50  (I chose 50 arbitrarily)
SET 1.5    #put the value 1.5 into the accumulator
STA 51    #store the value 1.5 in address 51
LDA 0      #input the number of hours worked
STA 52    #store the number of hours worked in address 52
LDA 0      #input the payrate
STA 53    #store the payrate at address 53
LDA 52   #load the number of hours worked into the accumulator
SUB 50   #subtract the number 40 (stored in address 50)
STA 54   #store overtime hours at address 54 
BRP RT   #if hours is more than 40, branch to overtime
LDA 50   #load 40 into the accumulator
MLT 53  #multiply by the payrate.
STA 55  #store REGULAR PAY pay in address 55
RT, LDA 52   #load the number of hours worked
LDA 54  #overtime hours
MLT 51 #overtime rate 
MLT 53 #payrate 
ADD 55 #add the regular pay 
STA 56 #all of the pay
BR FINAL  #branch to where you are going to print the week's pay
STA 56  #store total pay including regular pay and overtime pay in address 56
FINAL,STA 0  #output final pay
HLT

这里有什么问题，我该如何解决？

Answer 1

BRP RT   #if hours is more than 40, branch to overtime

如果工作小时数超过40，这个分支会跳过计算常规工资的代码。所以你现在正在做的是这样的：

if (overtime_hours <= 0) {
    regular_pay = 40 * pay_rate;
}
// Here regular_pay might not have been calculated
total_pay = overtime_hours * overtime_rate * pay_rate + regular_pay;

当你真正想要的东西可能是这样的时候：

regular_pay = 40 * pay_rate;
total_pay = regular_pay;
if (overtime_hours > 0) {
    total_pay = total_pay + overtime_hours * overtime_rate * pay_rate;
}
