Question

有没有人可以解答一下这一道题 是c语言编程的一道题

Assume that the variables rate_per_hr and tot_hrs contain an employee's hourly rate of pay and total hours worked during the week. Use an if statement to calculate the employee's gross pay for the week, using the rule that the first 40 hours worked are paid at rate_pr_hr, and any time over 40 hours is paid at rate_pr_hr * 1.5.

Answer 1

#include <stdio.h>

int main(void)
{
	double rate_per_hr,tot_hrs,gross_pay;
	scanf("%lf%lf",&rate_per_hr,&tot_hrs);
	if(tot_hrs>40)
	{
		gross_pay=40*rate_per_hr+(tot_hrs-40)*rate_per_hr*1.5;
	}
	else
	{
		gross_pay=tot_hrs*rate_per_hr;
	}
	printf("%lf\n",gross_pay);
	return 0;
}

大哥顺便问一下 这其实是一个问题来的 谢谢
Redo the above problem, but use conditional operators instead of the if statement.

#include <stdio.h>
 
int main(void)
{
    double rate_per_hr,tot_hrs,gross_pay;
    scanf("%lf%lf",&rate_per_hr,&tot_hrs);
    gross_pay=tot_hrs>40?40*rate_per_hr+(tot_hrs-40)*rate_per_hr*1.5:tot_hrs*rate_per_hr;
    printf("%lf\n",gross_pay);
    return 0;
}

Redo the above problem, but use a switch statement. Do not use conditional operators or if statements. Hint:如果choice是一个变量 程序就会把choice设为1如果有overtimepay，如果没有为0
choice = tot_hrs > 40;
