MFC 读取.dat文件 找到最后一行，并把最后一行 按照空格分开

在.h中声明
CString words[MAX_NUM];


void CHistogramDlg::ReadFile(CString filePath)

{
	FILE* f = fopen(filePath, "rt");
	char buf[1024];
	for (;;)
	{
		if (!fgets(buf, sizeof(buf) - 3, f))
			break;
		size_t len = strlen(buf);
		while (len > 0 && isspace(buf[--len]));
		buf[len + 1] = '\0';
	}

	CString recvBuffer = buf;; //被分割的字符串
	char* charpoint;
	charpoint = recvBuffer.GetBuffer(recvBuffer.GetLength());
	const char* split = "\t"; //分割符号
	char* p;
	p = strtok(charpoint, split); //分割字符串
	int i = 0;
	while (p != NULL)
	{
		words[i++] = p;
		p = strtok(NULL, split); //指向下一个指针
	}

	delete[] p;
	fclose(f);
}
