编程设计 从#include <iostream> #include <fstream> using namespace std; int main() { ofstream outfile("d:\\myfile3.txt",ios::app); if(outfile.fail()){ cout<<"D:\\file can not open"<<endl; return 1; } float x,y,z,a,b; cin>>a>>b>>x>>y>>z; outfile<<a<<" "<<b<<" "<<x<<" "<<y<<" "<<z<<endl; outfile.close(); return 0; }创建的文件中,把5个整数读取到变量或数组中,然后求和并输出到outfile1.txt文件中。

可以按照以下方式修改代码来实现您的需求:
```cpp
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ofstream outfile("d:\\myfile3.txt", ios::app);
if (outfile.fail()) {
cout << "D:\\myfile3.txt can not open" << endl;
return 1;
}
int nums[5]; // 用数组存储5个整数
cin >> nums[0] >> nums[1] >> nums[2] >> nums[3] >> nums[4];
int sum = 0;
for (int i = 0; i < 5; i++) {
sum += nums[i]; // 计算总和
}
ofstream outfile1("d:\\outfile1.txt");
if (outfile1.fail()) {
cout << "D:\\outfile1.txt can not open" << endl;
return 1;
}
outfile1 << sum << endl; // 将总和写入到outfile1.txt文件中
outfile1.close();
outfile.close();
return 0;
}
```
该程序将5个整数存储在一个数组中,然后将它们相加并将结果写入到outfile1.txt文件中。注意要先检查文件是否打开成功,否则程序会退出并输出错误消息。
