错误很离谱 ，求指教
astring::astring(const char *init){
int len=strlen(init);
maxsize=(len>defaultsize)?len:defaultsize;
ch=new char[maxsize+1];
if(ch==NULL){cerr<<"存储分配失败\n";exit(1);}
curlength=len;
strcpy(ch,init);
}



f:\p4_2\astring.h(28) : error C2143: syntax error : missing ')' before ';'
f:\p4_2\astring.h(28) : error C2059: syntax error : ')'
f:\p4_2\astring.h(28) : error C2143: syntax error : missing ';' before '?'
执行 cl.exe 时出错.

p4_2.exe - 1 error(s), 0 warning(s)
