C++ :

#include<bits/stdc++.h>
using namespace std;

void show(int n){
	for(int i = 1;i <= n;i++){
		cout<<"*";
	}
	cout<<endl;
}

int main(){
	int a[110];
	int n,i;
	cin>>n;
	for(i = 0;i < n;i++){
		cin>>a[i];
	} 
	
	for(i = 0;i < n;i++){
		cout<<i+1<<":";
		show(a[i]);
	} 
	
	 
    return 0;
}

Python :

# 接收输入
n = int(input())
a = input().split()
# 类型转换
for i in range(0, n):
    a[i] = int(a[i])
    # 输出序号
    print('%d:' % (i + 1), end='')
    # 输出*号
    for j in range(1, 11):
        if a[i] == j:
            print('*' * j)
