感谢您的关注

我试图创建一个类

long lPrime,lGenerator;
    lPrime = atol(vOut[1].c_str());
ZZ alicePrime;
    alicePrime = new ZZ(99999,lPrime);

我不确定 INIT_VAL_TYPE 要求我输入什么。

我收到了这个错误：

首先new是错误的。您不是在分配对象，而是在构造对象。

其次，假设我正在正确阅读头文件，并且假设我了解您要执行的操作，那么您只是想要

ZZ alicePrime(INIT_VAL, lPrime);

INTI_VAL只是一个常量，它强制编译器选择给出alicePrime初始值的构造函数，而不是说，初始位大小。

NTL 文档很差。
