Heap

[Ken Mazaika]

Within a class I need to have an object in the heap. Within the constructor I make a new object and I can access the data members. When I try to access them in different member functions however I get memory access errors. I call the delete in the destructor, and not before. I'm not sure what is wrong.

Could you post your code?

Here's your problem: In CParticleEngine::init(int nParticles) you have the following line: CParticle *m_pParticles = new CParticle[nParticles]; Change it to m_pParticles = new CParticle[nParticles]; and your code will work. By declaring the m_pParticles variable again in the init() function, you have made a new variable that only has scope in the init() function, and happens to be named the same as your member variable m_pParticles. Thus the member variable never gets assigned, and you (rightfully) get memory errors when you later try and delete it. --Dean

while(nCount != nParticles) should be while(nCount < nParticles) //0 based indexes in C++

Excellent. Thanks a bunch!
