修改代码#include <iostream> using namespace std; int f(int y, int m) { if (y % 4 == 0 || y % 100 != 0) { switch (m) { case 1: return 31; case 2: return 29; case 3: return 31; case 4: return 30; case 5: return 31; case 6: return 30; case 7: return 31; case 8: return 31; case 9: return 30; case 10: return 31; case 11: return 30; case 12: return 31; } } if (y % 400 == 0) { switch (m) { case 1: return 31; case 2: return 29; case 3: return 31; case 4: return 30; case 5: return 31; case 6: return 30; case 7: return 31; case 8: return 31; case 9: return 30; case 10: return 31; case 11: return 30; case 12: return 31; } else { switch (m) { case 1: return 31; case 2: return 28; case 3: return 31; case 4: return 30; case 5: return 31; case 6: return 30; case 7: return 31; case 8: return 31; case 9: return 30; case 10: return 31; case 11: return 30; case 12: return 31; } } }

使用include <iostream>时一定要加using namespace std
这段代码是一个计算特定年份和月份天数的函数,其中包括了判断闰年的逻辑。但是,代码存在一个语法错误,导致无法编译通过。具体来说,if语句的括号没有匹配,导致编译器报错。
以下是修改后的代码:
```
#include <iostream>
using namespace std;
int f(int y, int m) {
if (y % 4 == 0 || y % 100 != 0) {
switch (m) {
case 1:
return 31;
case 2:
return 29;
case 3:
return 31;
case 4:
return 30;
case 5:
return 31;
case 6:
return 30;
case 7:
return 31;
case 8:
return 31;
case 9:
return 30;
case 10:
return 31;
case 11:
return 30;
case 12:
return 31;
}
} else if (y % 400 == 0) {
switch (m) {
case 1:
return 31;
case 2:
return 29;
case 3:
return 31;
case 4:
return 30;
case 5:
return 31;
case 6:
return 30;
case 7:
return 31;
case 8:
return 31;
case 9:
return 30;
case 10:
return 31;
case 11:
return 30;
case 12:
return 31;
}
} else {
switch (m) {
case 1:
return 31;
case 2:
return 28;
case 3:
return 31;
case 4:
return 30;
case 5:
return 31;
case 6:
return 30;
case 7:
return 31;
case 8:
return 31;
case 9:
return 30;
case 10:
return 31;
case 11:
return 30;
case 12:
return 31;
}
}
}
```
修改的主要内容是在第一个if语句后增加了一个else if语句,用于判断闰年。这样就修复了括号不匹配的问题,并且代码逻辑也更加清晰了。
