编写一个程序，输入n个正整数到数组中，其中1≤n≤1000。然后用柱状图的形式将这些值表示出来。

有帮助的话 采纳一下

#include <iostream> 
#include <algorithm>
using namespace std;

int main() {
    int n;
    cin >> n;
    int arr[n];
    for (int i = 0; i < n; i++) {
        cin >> arr[i];
    }
    
    sort(arr, arr + n);
    
    int maxNum = arr[n - 1];
    int count[maxNum + 1] = {0};
    
    for (int i = 0; i < n; i++) {
        count[arr[i]]++;
    }
    
    for (int i = maxNum; i >= 1; i--) {
        if (count[i] > 0) {
            for (int j = 0; j < count[i]; j++) {
                cout << "*";  
            }
            cout << endl;
        }
    }
} 

运行效果如图

代码如下 , 如有帮助给个采纳谢谢

#include <iostream>
using namespace std;

int main() {
    int n, maxVal = 0;
    cout << "请输入正整数的个数n：";
    cin >> n;

    int arr[n];
    for (int i = 0; i < n; i++) {
        cout << "请输入第" << i+1 << "个正整数：";
        cin >> arr[i];
        if (arr[i] > maxVal) {
            maxVal = arr[i];
        }
    }

    cout << endl << "柱状图如下：" << endl;
    for (int i = maxVal; i > 0; i--) {
        for (int j = 0; j < n; j++) {
            if (arr[j] >= i) {
                cout << "* ";
            } else {
                cout << "  ";
            }
        }
        cout << endl;
    }
    for (int i = 0; i < n; i++) {
        cout << "- ";
    }
    cout << endl;
    for (int i = 0; i < n; i++) {
        cout << arr[i] << " ";
    }
    cout << endl;

    return 0;
}
