行数未知我想把第一列的数字（x后面的）读取到数组x中，第二列的到y中，第三列的到z中该怎么操作，同时还想知道每个数组里有多少数

Answer 1

CStdioFile::ReadString();
CString::Tokenize()以空格分隔字符串

Answer 2

CStdioFile.ReadString
分析字符串"-"

Answer 3

CStdioFile fp;
fp.Open("kao.txt",CFile::modeRead);
CString line,str1,str2;
int pos1,pos2;
while(!fp.ReadString(line))
{
   str1=line.Mid(1);//去掉X
   pos1=str1.Find(" ");//查找空格
    x=str1.Left(pos1);
   pos2=str1.Find(" ",pos1+1);//查找空格
   y=str1.Mid(pos1+1,pos2-pos1-1);   z=str1.Mid(pos2+1);
}

Answer 4

数组读取的问题解决了，
每个数组里有多少数（txt有多少行）怎么解决

Answer 5

std::vector
std::string
str::string::find std::string::substr

Answer 6

用一个变量记录读了多少行，每次ReadString之后加1，就可以啦

Answer 7

建议不要用数组，因为数组个数固定，可以考虑
std::vector
