When the pressure gets high enough, the carbon will fuse into oxygen, and these changes will continue as heavier and heavier elements are fused. This process stops when iron builds up in the core of the star. Iron is the equivalent of ash when it comes to nuclear fusion. The process of fusing iron actually requires more energy than it releases.
