C++基础-两头堵挖字符串

两头堵挖字符串

void TrimLeft_RightSpace(char *m_inBuf, char *m_outbuf)
{
	int i = 0;
	int j = strlen(m_inBuf)-1;
	while (m_inBuf[i++] == ' ' && m_inBuf !='\0')
	{}

	while (m_inBuf[j--] == ' ' && m_inBuf != '\0')
	{}

	int ncount = j - i + 1;
	memcpy(m_outbuf, m_inBuf+i,ncount);
	m_outbuf[ncount] = '\0';

}


void main()
{
	int count = 0;
	char *p = "     asderfghjlerjjiujer12     ";
	char buf[24] = { 0 };
	TrimLeft_RightSpace(p, buf);
	cout << "原来:|" << p << "|"<<endl;
	cout << "去掉前后空格:|" << buf <<"|"<< endl;
	system("pause");

}

结果:
