c++ 代码学习1

学习代码： https://github.com/mortenpi/detector-schmector

1. 安装gsl

   sudo apt search libgsl
   sudo apt-get install libgsl-dev
   g++ test_gsl.cpp -o lala -lgsl -lgslcblas

2. 定义类

   • 在头文件定义类, 在cpp文件中具体定义
   • 定义基类的基本函数函数定义用 virtual
   • 子类构造函数可以用父类的构造函数 classB::classB(int b,int a):classA(a){}

     class Distribution
     {
     public:
     Distribution
     virtual double pdf(double x) = 0;
     virtual double cdf(double x) = 0;
     };

class NormalDistribution:public Distribution{
double A, B, mean;
public:
NormalDistribution(double mean, double stdev);
double pdf(double x);
double cdf(double x);
};

NormalDistribution::NormalDistribution(double mean, double stdev)
{
this->mean = mean;
this->A = stdev + mean;
this->B = mean *mean;
}

Distribution * dist = new NormalDistri(0.2);
