錯誤 2 error LNK1120: 1 個無法決議的外部命令
錯誤 1 error LNK2019: 無法決議的外部符號 "public: __thiscall n1::n1(void)" (??0n1@@QAE@XZ)，該符號在函式 _main 中被參考
uj5u.com熱心網友回復：
class n1 :public M{
public:
n1();
double count1(double x)
{
m = x;
as1 = m *(1000000)/ (a1*fc*b1*ho*ho);
temp1 = sqrt(1 - 2 * as1);
T1 = 1 - temp1;
As1 = T1*b1*ho*a1*fc / fy;
cout << "as1="<<as1<<endl;
cout << "T1=" << T1<<endl;
cout << "As1=" << As1<<endl;
return 0;
};
好像是這個有問題，
是繼承出錯了嗎？
