实在没看出来哪里的问题

@[KingRan](/user/300205) 当n<=150时，第二个判断中给sum赋的值会取代第一个判断中赋的值
by lpk1118 @ 2024-01-02 20:13:12
```
cin >> n;
if (n <= 150)
{
sum = n * 0.4463;
}
if (n >= 151 && n <= 400)
{
sum = (n - 150) * 0.4663 + 150 * 0.4463;
}
else
{
sum = (n - 400) * 0.5663 + 150 * 0.4463 + (400 - 151 + 1) * 0.4663;
}
```
改为：
```
cin >> n;
if (n <= 150)
{
sum = n * 0.4463;
}
else if (n >= 151 && n <= 400)
{
sum = (n - 150) * 0.4663 + 150 * 0.4463;
}
else
{
sum = (n - 400) * 0.5663 + 150 * 0.4463 + (400 - 151 + 1) * 0.4663;
}
```
