[c++] Another C++ pointer problem

Particle* particlePtr = new Particle(p0);

P.push_back(*particlePtr);
BreakableSpringForce2Particle* force2Ptr1 = new BreakableSpringForce2Particle(psb.PS.getParticlePtr(currIdx-1), particlePtr, &psb.PS, SPRING_BREAK_THRESHOLD);
psb.PS.F.push_back(force2Ptr1);
BreakableSpringForce2Particle* force2Ptr2 = new BreakableSpringForce2Particle(psb.PS.getParticlePtr(i*latitude), particlePtr, &psb.PS, SPRING_BREAK_THRESHOLD);

psb.PS.F.push_back(force2Ptr2);

// when force2Ptr2 update the particle through its ‘particlePtr’, it will writes to the corresponding particle in the P deque and overrides the changes done by force2Ptr1 previously.
// as if force2Ptr1 and force2Ptr2 maintain their own copy of the particle as well as can have change propogate to the particle on the P
