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;
}

Pascal :

var a:array[1..100000] of longint;
    n,i,j:longint;
begin
read(n);
for i:=1 to n do
read(a[i]);
for i:=1 to n do
begin
write(i,':');
for j:=1 to a[i] do
write('*');
writeln;
end;
end.

Java :

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int[] a =new int[n];
		for (int i =0;i<n;i++) {
			a[i]=sc.nextInt();
		}
		for (int i =0;i<n;i++) {
			System.out.print(i+1+":");
			for (int j=1;j<=a[i];j++) {
				System.out.print("*");
			}
			System.out.println();
		}
	}
}

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)
