int型它有限制数值大小为-32768~32767,大于就会出错，应该使用long int

貌似对入门来说难了点啊!~

哪位写出了第一题，帮忙帖一下，谢谢了。[em18]

第一题答案:

#include<iostream>

using namespace std;

int main()
{
    int a,b,c,d,e,f,g,x,y,z,i,j;
    int num1,num2,sum;
    int count[10]={ 0,0,0,0,0,0,0,0,0};
    bool multi_number = false;

    for( a=1 ; a<=9 ; a++ )
    {
        count[a]++;

        for( b=0 ; b<=9 ; b++)
        {
            if( count[b]>0 )
            {
                continue;
            }

            count[b]++;

            for( c=0 ; c<=9; c++ )
            {

                if( count[c]>0 )
                {
                    continue;
                }
                
                count[c]++;

                for( d=1 ; d<=9 ; d++ )
                {
                    if( count[d]>0 )
                    {
                        continue;
                    }

                    count[d]++;
