从键盘上输入软干个数字要求按递减排序并将结果写入指定文件中C++

#include #include #include #include

using namespace std;

int main() { int n; cout << "请输入数字的个数：" << endl; cin >> n;

vector<int> nums(n);
cout << "请输入数字：" << endl;
for (int i = 0; i < n; i++) {
    cin >> nums[i];
}

sort(nums.rbegin(), nums.rend()); // 递减排序

ofstream outfile("result.txt");
for (int i = 0; i < n; i++) {
    outfile << nums[i] << " ";
}

cout << "结果已写入文件result.txt" << endl;

return 0;

}
