修改#include <iostream> #include <cstring> using namespace std; void DisMonths(char p[][30]){ for (int i=0;i<12;i++){ cout<<p[i]<<endl; } } void SortStrings(char p[][30],int n){ char temp; for (int i=0;i<12;i++){ if (strcmp(p[i],p[i+1])>0){ temp=p[i]; p[i]=p[i+1]; p[i+1]=temp; } } } int main(){ char months[12][30]={"January","February","March","April","June","July","August","September","October","November","December"}; cout<<"排序前:"<<endl; DisMonths(months); SortStrings(months,12); cout<<endl<<"排序后:"<<endl; DisMonths(months); return 0; }使其能满足对月份按字符串顺序输出

修改后的代码如下:
```cpp
#include <iostream>
#include <cstring>
#include <algorithm>
using namespace std;
void DisMonths(char p[][30]){
for (int i = 0; i < 12; i++){
cout << p[i] << endl;
}
}
void SortStrings(char p[][30],int n){
sort(p, p + n);
}
int main(){
char months[12][30] = {"January","February","March","April","June","July","August","September","October","November","December"};
cout << "排序前:" << endl;
DisMonths(months);
SortStrings(months, 12);
cout << endl << "排序后:" << endl;
DisMonths(months);
return 0;
}
```
修改说明:
1. 将原来的头文件 `<cstring>` 替换成 `<algorithm>`,以便使用 STL 中的 `sort` 函数。
2. 在 `SortStrings` 函数中,直接调用 `sort` 函数进行排序。
3. 去掉了原来的冒泡排序代码,因为 `sort` 函数可以直接对字符串数组进行排序。
这样修改后,就可以满足对月份按字符串顺序输出的要求了。
