首次适应算法c++实现

根据提供的引用[1]，以下是首次适应算法的C++实现：

#include<iostream>
using namespace std;

struct Job {
    string name;
    int size;
    int start;
};

struct Blank {
    int size;
    int start;
};

int main() {
    int n, m;
    cout << "请输入空闲区的数量：";
    cin >> n;
    Blank blanks[n];
    for (int i = 0; i < n; i++) {
        cout << "请输入第" << i + 1 << "个空闲区的大小和起始地址：";
        cin >> blanks[i].size >> blanks[i].start;
    }
    cout << "请输入作业的数量：";
    cin >> m;
    Job jobs[m];
    for (int i = 0; i < m; i++) {
        cout << "请输入第" << i + 1 << "个作业的名字和大小：";
        cin >> jobs[i].name >> jobs[i].size;
        bool flag = false;
        for (int j = 0; j < n; j++) {
            if (blanks[j].size >= jobs[i].size) {
                jobs[i].start = blanks[j].start;
                blanks[j].start += jobs[i].size;
                blanks[j].size -= jobs[i].size;
                flag = true;
                break;
            }
        }
        if (!flag) {
            cout << "内存不足，作业" << jobs[i].name << "无法分配内存" << endl;
        }
    }
    cout << "作业分配情况如下：" << endl;
    for (int i = 0; i < m; i++) {
        cout << "作业" << jobs[i].name << "的起始地址为" << jobs[i].start << endl;
    }
    return 0;
}
