C++ 雜筆記

最近剛好有朋友問了一個程式的小題目，
正好之前3月的問題，也和這個類似，
不過那時候沒時間，也 留到現在了。

1.cin 緩衝區問題：

http://hi.baidu.com/liuhaorancode/blog/item/7740ae1b5942381f8618bf09.html

code:

加入cin.ignore(1,' ');

str and str2 is char

    cin.get(str,999,'\n');

    cxList->scan(str);

    cin.ignore(1,' ');

    cin.get(str2,999,'\n');

    cxList2->scan(str2);

2.strtok() 使用

3.sstream stringstream 字串轉數字

4.使用vector

template < class T, class Allocator = allocator > class vector;

參考：

http://www.cplusplus.com/reference/stl/vector/

http://www.cnblogs.com/oomusou/archive/2008/03/22/1117686.html

code:

#include

...略.

class cx_List{+

.. 略..

vector viValue;

void scan(char* str);

stringstream strStream;

.. 略..

void

    cx_List::scan(char* str)

{

    char *cp;

    int i = 0,tmp = 0;

    //cout << str << endl;

    cp = strtok(str," ");

    while(cp != NULL)

    {

        //printf ("cp:%s\n",cp);

        this->strStream << cp;

        this->strStream >> tmp;

        //cout << tmp << endl;

        this->viValue.push_back(tmp);

        cp = strtok(NULL," ");

        this->strStream.clear();

        i++;

    }

}

};
