编写一个进程调度程序,实现基于优先权的进程调度算法,要求:输入n个进程的信息:ID,进程名,优先级以及运行时间

以下是一个基于优先权的进程调度程序的示例代码,使用C++语言编写:
```c++
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
struct Process {
int id;
string name;
int priority;
int runtime;
};
bool compare(Process a, Process b) {
return a.priority > b.priority;
}
int main() {
int n;
cout << "请输入进程数:";
cin >> n;
vector<Process> processes(n);
for (int i = 0; i < n; i++) {
cout << "请输入第" << i+1 << "个进程的信息(ID 进程名 优先级 运行时间):";
cin >> processes[i].id >> processes[i].name >> processes[i].priority >> processes[i].runtime;
}
sort(processes.begin(), processes.end(), compare);
cout << "进程调度顺序: ";
for (int i = 0; i < n; i++) {
cout << processes[i].name << " ";
}
return 0;
}
```
该程序首先读入n个进程的信息,然后根据进程的优先级排序,最后输出按顺序调度的进程名。
注意:这只是一个基于优先权的简单示例程序,实际的进程调度算法可能更复杂,需要考虑多个因素,如进程的运行时间、等待时间、IO请求等。
