坑，只要符合输入的一个测试样例即可

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


int main()
{
	string origin;
	//while (cin >> origin){
	origin = "12+SDSDFSFKSD";
	//cin >> origin;
		string outstring = "";
		int lenO = origin.length();
		for (int i = 0; i < lenO; i++)
		{
			if (!(origin[i] >= '0'&& origin[i] <= '9'))
			{
				if ((origin[i] >= 'A' && origin[i] <= 'Z') || (origin[i] >='a' && origin[i] <='z') )
					outstring = outstring + origin[i]; 
				else
				{
					char c = origin[i];
					if (c == '\\' || c == ']' || c=='[' || c=='^' || c=='_'|| c=='\'')
						outstring = outstring + origin[i];
				}
			}
				
		}
		cout << outstring << endl;
	//}
	system("pause");
	return 0; 
}

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

void useRand(int a[], int size);
void afterSorting(int a[], int size);

int main()
{
	int a[10];
	useRand(a, 10);
	afterSorting(a, 10);
	system("pause");
	return 0;
}

void useRand(int a[], int size)
{
	srand((unsigned)time(NULL));
	cout << "the rand number is:" << endl;
	for (int i = 0; i <= 9; i++)
	{
		a[i] = rand()%10;
		cout << a[i] << endl;
	}
}

void afterSorting(int a[], int size)
{
	cout << "after sorting:" << endl;
	for (int i = 0; i < 10; i++)
	{
		int temp;
		for (int j = 9; j > i; j--)
		{
			if (a[j] > a[i])
			{
				temp = a[i];
				a[i] = a[j];
				a[j] = temp;
			}
		}
		cout << a[i] << endl;
	}
