I am trying to create a class in C++ (I have not worked with classes in a long time!) and I am trying to create a few constructors in the following way:
#ifndef TAAP_HEAD
#define TAAP_HEAD
class TaaP
{
public:
// default cosntructor
Taap();
// constructor with xyz
Taap(double xyz[3]);
private:
double m_xyz[3];
double m_Rho;
double m_GradRho[3];
double m_HessRho[3][3];
double m_EigenValues[3];
double m_EigenVectors[3][3];
};
#endif
where Taap() will simply assign xyz to {0.0, 0.0, 0.0}, but Taap(double xyz[3]) will allow the user to input their own starting coordinate.
The error I get upon compilation is :
hdr_taap.h:9:8: error: ISO C++ forbids declaration of ‘Taap’ with no type [-fpermissive]
Taap();
^
hdr_taap.h:12:21: error: ISO C++ forbids declaration of ‘Taap’ with no type [-fpermissive]
Taap(double xyz[3]);
^
Does this make any sense? I have tried to follow a lot of examples of class construction and cannot see anything I am doing wrong.
C++ is case-sensitive. Change TaaP to Taap
