新起点

qiushao — Mon, 13 May 2013 06:25:00 GMT

自从去年9月开始，c++博客便荒废了！时光荏苒，大半年了！
希望重新顶起吧。
一直困难的一个问题，没成想很弱智。
问题如下：I have a complex program which runs fine in Debug mode in Visual Studio 2008.
When I run it in Release mode, it crashes immediately with "Debug assertion failed in Visual Studio 9.0\VC\include\vector Line 70".
Is there any way I can run the program inside Visual Studio 2008 so I can see stack trace?
Any other tips on this issue?

There are no debug assertions in a release build.
Maybe you are accidentally using a DLL or library that is built in debug mode. All linked modules must be release builds, or all debug builds. You can't mix the two types.
汗颜！

非四则运算计算两整数和

qiushao — Tue, 04 Sep 2012 09:12:00 GMT

int _tmain(int argc, _TCHAR* argv[])
{
    int a=2,b=3;
    printf("%d",printf("%*s%*s",a,"",b,""));
    return 0;
}

判断一整数是否回数（对称）

qiushao — Sat, 01 Sep 2012 13:03:00 GMT

bool symmetry(long a)
{
    long i,temp;
    temp=0,i=a;
    while(i)
    {
        temp=10*temp+i%10;
        i=i/10;
    }
    return (temp==a);
}
int _tmain(int argc, char* argv[])
{
    long i=12345;
    cout<<symmetry(i)<<endl;
    return 0;
}

文本大写转小写

qiushao — Sun, 08 Jul 2012 08:15:00 GMT

int _tmain(int argc, char* argv[])
{
    string s;
    vector<string> svec;
    cout<<"please enter words(enter ctrl+z quit):"<<endl;
    while(cin>>s)
        svec.push_back(s);
    vector<string>::iterator it=svec.begin();
    int cnt(0);
    while(it!=svec.end())
    {
        for(int i=0;i!=(*it).length();i++)
        {
            (*it)[i]=toupper((*it)[i]);
        }
        cout<<*it<<" ";
        cnt++;
        if(cnt%4==0)
            cout<<endl;
        it++;

    }
    return 0;

关于windows相关头文件

qiushao — Thu, 07 Jun 2012 02:46:00 GMT

windows.h里包括windef.h winbase.h windgdi.h winuser.h
windows API太多、太复杂，很多文件很大的关联性，如果要使用到windows相关头文件，还是包含windows.h吧
不知为什么仅仅#include
编译有错
windef.h里有定义DWORD BYTE 等等

c语言头文件组织

qiushao — Thu, 07 Jun 2012 01:37:00 GMT

定义一个var-Global.c 定义全局变量然后在var-Global.h 声明全局变量
哪个文件用到了这些全局变量就在aa.h 文件里#include"var-Global.h" 然后在这个头文件里声明必要的接口函数
extern void fun();
在aa.c文件里只要 #include"aa.h"

数组放在堆里

qiushao — Fri, 01 Jun 2012 06:53:00 GMT

相对于放在栈里的优点：可以在运行时确定数组长度

int* createArr()
{
    cout<<"shuru size:"<<endl;
    size_t size;
    cin>>size;
    int* arr=new int[size];
    cout<<sizeof(arr)<<endl;
    return arr;
}
int _tmain(int argc, _TCHAR* argv[])
{
    //int *p;
    //p=createArr();
    createArr();
    return 0;
}

在一个字符串中查找第一个只出现一次的字符

qiushao — Tue, 22 May 2012 11:42:00 GMT

哈希表实现：
char find(char *p)
{
    if(p==NULL)
    {
        cout<<"error"<<endl;
        return -1;
    }
    const int size=256;
    int hashTable[size]={0};
    char *key=p;
    while(*(key)!='\0')
    {
        hashTable[*key++]++;
    }
    key=p;
    while(*key!='\0')
    {
        if(hashTable[*key]==1)
            return *key;
        key++;
    }
    cout<<"All char are repeat!"<<endl;
    return -1;
}
int _tmain(int argc, _TCHAR* argv[])
{
    char s[]="abdaccdbeef";
    cout<<find(s)<<endl;
    return 0;
}

char findone(string &s)
{
    int len=s.size();
    int i;
    for(i=0;i<len;i++)
    {
        int beg=s.find(s[i]);
        int end=s.find_last_of(s[i]);
        if(beg==i&&end==i)
        {
            break;
        }
    }
    if(i==len)
        {
            cout<<"Not found!"<<endl;
            return -1;
        }
    else
        return s[i];

}
int _tmain(int argc, _TCHAR* argv[])
{
    string s("abdaccbeff");
    cout<<findone(s)<<endl;
    return 0;
}
