POI are the points where bending moment equals zero.
POC are the points where bending moment changes the sign.
So, all POC are POI, but all POI are not POC.

Contraflexure means the point where BM changes sign or becomes 0.
Inflection means the point in the beam where the deflected shape changes, either from hogging to sagging or saaging to hogging.

Inflection point ----- it is the point, where S.F is 0 or change its sign.
Contraflexure point ----it is the point, where B.M is 0 or change its sign.

The point of inflection is BM is 0.
The point of contraflexure is BM is 0 and change its sign.
That is all point of contraflexures are the point of infletion but all point of infletion are not point of contraflexure.
Hope you understand.

Generally, Point of cocontra flexure Point of inflexion these are same, inflexion is the word of math which means curve change own sign and contraflexure is the word from Mechanics.
