输入n组数，进行排序，输入一组排序一组。

C/C++代码：

#include <iostream>
#include <string>
#include <stdio.h>

using namespace std;

int main()
{
	//输入n组数
	int n,cont;
	int temp;

	cout << "Input group number:";
	cin >> n;

	while(n--){  //每次输入一组数

		int ch[20];
		char c;
		
		for (int i=0; i<20; i++){
			scanf("%d%c",&ch[i],&c);//回车，一行表一组
			if(c=='\n'){ //遇到回车退出
				cont = i+1;
				//cout << "cont" << cont << endl;
				break;
			}
			//cout << "ch" << ch[i] << endl;
		}

		//冒泡排序
		for (int j=0; j<cont; j++){
			for(int i=0; i<cont-j; i++){
				//cout << "ch=" << ch[i] << " ";
				if (ch[i]>ch[i+1]){
					temp=ch[i];
					ch[i]=ch[i+1];
					ch[i+1]=temp;
				}
			}
		}

		//循环输出ch数组
		for (int i=0; i<cont; i++){
			cout << ch[i] << " ";
		}
			cout << endl;

	}
	return 0;
}
