以下是已经改正的代码:
```cpp
#include <iostream>
#include <fstream>
using namespace std;
class DIF {
private:
int low, high;
int a[100];
int count;
public:
DIF(int lw = 10, int hi = 1000) {
low = lw;
high = hi;
}
int isdiff(int x) {
int sum = 0;
int temp = x;
while (temp > 0) {
int digit = temp % 10;
sum += digit * digit * digit;
temp /= 10;
}
return (sum == x);
}
void process() {
count = 0;
for (int x = low; x <= high; x++) {
if (isdiff(x)) {
a[count++] = x;
}
}
}
void show() {
cout << "满足条件的数字有:" << endl;
for (int i = 0; i < count; i++) {
cout << a[i] << " ";
}
cout << endl;
cout << "满足条件的数字个数为:" << count << endl;
ofstream outf("bc02.in");
if (outf.is_open()) {
for (int i = 0; i < count; i++) {
outf << a[i] << " ";
}
outf << endl;
outf << "count=" << count;
outf.close();
} else {
cout << "无法打开文件bc02.in" << endl;
}
}
};
int main() {
DIF v(100, 999);
v.process();
v.show();
return 0;
}
```
这段代码进行了以下修改:
1. 包含头文件 `<iostream>` 和 `<fstream>` 的语句已更正为 `<iostream>`。
2. `main` 函数的返回类型更正为 `int`。
3. 在 `isdiff` 函数中,修正了计算每位数字立方和的错误。
4. 在 `show` 函数中,修正了打开文件 `bc02.in` 的逻辑,并添加了对文件打开状态的检查。
请注意,这段代码仅仅是对您提供的代码进行了修正,可能还存在其他潜在的错误。建议您仔细检查并测试代码以确保其正常运行。
