  • c\c++ 中字符串分割,并且转换为整形数据

      在项目开发中,经常使用到字符串分割, 并且将其转换为整形(比如IP的分割获取,MAC地址的分割获取等),代码如下:

    #ifndef _UNICODE
        void StrToIntData( char *pStr,int nIntData[],const char * pTok )
        {
    
            char *pStrPos = NULL;
            char *pNextToken = NULL;
            int nPos = 0;
    
            pStrPos = strtok_s(pStr,pTok,&pNextToken);
    
            while (pStrPos) 
            {
                nIntData[nPos] = atoi(pStrPos);
                nPos ++;
                pStrPos = strtok_s(NULL,pTok,&pNextToken);
            } 
    
        }
    
        char * IntToStrData(int nData)
        {
            static char str[MAX_PATH] = {0};
            itoa(nData,str,10); 
            return str;
        }
    
    #else
        void StrToIntData( wchar_t *pStr,int nIntData[],const wchar_t * pTok )
        {
    
            wchar_t *pStrPos = NULL;
            wchar_t *pNextToken = NULL;
            int nPos = 0;
    
            pStrPos = wcstok_s(pStr,pTok,&pNextToken);
    
            while (pStrPos) 
            {
                nIntData[nPos] = _ttoi(pStrPos);
                nPos ++;
                pStrPos = wcstok_s(NULL,pTok,&pNextToken);
            } 
    
        }
    
        wchar_t * IntToStrData(int nData)
        {
            static  wchar_t str[MAX_PATH] = {0};
            _itot(nData,str,10); 
            return str; 
        }
    
    #endif
