解题思路：直接用阿斯科马值，大写字母的阿斯科马值加上32就是小写字母。

代码：

#include<iostream>

#include<cstring>

#include<string>

using namespace std;

char str[1005];

int main()

{

    while(cin.getline(str,1005))

    {

        for(int i=0;i<strlen(str);i++)

        {

            if((str[i]>='A')&&(str[i]<='Z'))

                str[i]+=32;

       }

        cout<<str<<endl;

        memset(str,'\0',sizeof(str));

    }

    return 0;

}

解题感想：这题主要涉及到用C++在字符数组中输入空格，而且涉及多组样例。搞定了输入一切ok。
