C语言实现去除字符串中空格

去除字符串中所有空格

voidVS_StrTrim(char*pStr)

{

char *pTmp = pStr;

while (*pStr != '/0')

{

if (*pStr != ' ')

{

*pTmp++ = *pStr;

}

++pStr;

}

*pTmp = '/0';

}

去除字符串右边空格

void VS_StrRTrim(char *pStr)

{

char *pTmp = pStr+strlen(pStr)-1;

while (*pTmp == ' ')

{

*pTmp = '/0';

pTmp--;

}

}

去除字符串左边空格

void VS_StrLTrim(char *pStr)

{

char *pTmp = pStr;

while (*pTmp == ' ')

{

pTmp++;

}

while(*pTmp != '/0')

{

*pStr = *pTmp;

pStr++;

pTmp++;

}

*pStr = '/0';

}

然后用方法一我转了一个全是int 类型的DateTime类，代码很难看

string DateTime::toString()

{

char temp1[100],temp2[20];

sprintf(temp1, "%d", this->year);

sprintf(temp2, "%d", this->month);

strcat(temp1,temp2);

sprintf(temp2, "%d", this->day);

strcat(temp1,temp2);

sprintf(temp2, "%d", this->hour);

strcat(temp1,temp2);

sprintf(temp2, "%d", this->minute);

strcat(temp1,temp2);

sprintf(temp2, "%d", this->second);

strcat(temp1,temp2);

sprintf(temp2, "%d", this->milliSecond);

strcat(temp1,temp2);

string str(temp1);

return str;

}
