Question

我有字符串
char *pbuf='asdhadfsohasodfgaosgdoiuwqeiureuasdasdasd'；如何从pbuf左边依次取5位字符

Answer 1

CString rrr;
rrr=buf;
CString kkk;
kkk=rrr.Left(5);

Answer 2

char strItem[6];strncpy(strItem,pbug,5);
strItem[5]='\0';

Answer 3

char newchar;
for(int index=0;index<5;index++)
{
    newchar=pbuf[index];
}

Answer 4

pbuf="asdljapldfjapsdfgaposgjasjgasgjasjgjafjag";
我的意思是第一次取‘asdlj’,第二次取‘apldf’,第三次取‘japsd’怎样写个循环

Answer 5

int nCount;
int nIndex=0;
char strItem[6];
nCount=strlen(pbuf);
while(nIndex<nCount)
{
    if(nIndex+5<nCount)
        strncpy(strItem,pbuf,nIndex,5);    else
        strncpy(strItem,pbuf,nIndex,nCount-1);
    strItem[5]='\0';
    nIndex+=5;
}

Answer 6

出错
strncpy' : function does not take 4 parameters

Answer 7

int nCount;
int nIndex=0;
CString ret;
CString kkk;
kkk=pbuf;
nCount=strlen(pbuf);
while(nIndex<nCount)
{
    if(nIndex+5<nCount)
        ret=kkk.Mid(nIndex,nIndex+5);
    else
        ret=kkk.Mid(nIndex,nCount)
    nIndex+=5;
}
