嗨，我对这个代码有问题，我完成了代码，但不知怎么的，我的电荷和气体电荷输出与我的教授使用的测试运行输出不同，我想我可能没有使用正确的公式来计算气体电荷和电荷。有人能给我看一下计算气量和电荷的正确公式吗
这是我的输出
Enter previous & current electric meter readings: 80000
80500
Enter previous & current gas meter readings: 990
1030
Electric:
Previous: 80000, Current: 80500, KWH Used: 500, Charges: 210.73
Gas:
Previous: 990, Current: 1030, Therms Used: 40, Charges: 104.14
Total Charges: 314.87
Process returned 0 (0x0) execution time : 21.512 s
Press any key to continue.
这是测试运行输出：
Enter previous & current electric meter readings: 80000
80500
Enter previous & current gas meter readings: 990
1030
Electric:
Previous: 80000, Current: 80500, KWH Used: 500, Charges: 135.78
Gas:
Previous: 990, Current: 1030, Therms Used: 40, Charges: 135.78
Total Charges: 271.56
正如你所看到的，在使用相同的输入时，气体电荷和电荷的输出是不同的。我该怎么解决？
最佳答案
你不能指望有人知道你想使用什么公式：）但我认为你的问题在于代码而不是公式。试试这个：
double calcElecCharges(double* kwhConSumed)
{
double elecCharge ;
if (*kwhConSumed > 0 && *kwhConSumed <= BASELINE)
{
elecCharge = *kwhConSumed * CONST1;
}
else
{
if ( *kwhConSumed > BASELINE && *kwhConSumed <= (1.3*BASELINE))
{
elecCharge = *kwhConSumed * CONST2;
}
else
{
if ( *kwhConSumed > (1.3*BASELINE) && *kwhConSumed <= (2.0*BASELINE))
{
elecCharge = *kwhConSumed * CONST3;
}
else if (*kwhConSumed > 2.0*BASELINE)
{
elecCharge = *kwhConSumed * CONST4;
}
else
{
//*kwhConSumed < (1.3*BASELINE) || *kwhConSumed > (2.0*BASELINE)
//What now??
}
}
}
return round100th(elecCharge);
}
double calcGasCharges(double thermsConsumed)
{
double gas;
// check if therms < 0 and <= baseline
if (thermsConsumed > 0 && thermsConsumed <= GAS_BASELINE)
gas = thermsConsumed * CONST5;
else if (thermsConsumed > GAS_BASELINE)
gas = thermsConsumed * CONST6;
else
{
//thermsConsumed < 0
//What now??
}
return round100th(gas);
}
或者提供你从教授那里得到的公式以便有人检查你的代码。
