Following the IUPAC definition method (typically taught in the US) O is with few exceptions -2 , H is +1 in this instance (it is only -1 when linked to a reactive metal). Therefore as the overall oxidation state of the molecule is zero as it is uncharged the oxidation number of C is 0.
Other answers are possible as there are other ways to work it out
a previous contributor offered this answer:-
To get the oxidation number for COH2 can be calculated by adding the oxidation of the individual elements. COH2 C is (+4), 2H is (-2) and O is (-2) which equals to 0.

What is the oxidation number of acetate?
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
What is the oxidation number of H2CO2?
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
What is the oxidation number of nitrosyl?
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
What is the oxidation number for Nb in NbO2?
Oxidation number of Nb is +4. Oxidation number of O is -2.
What is the oxidation number of H2O2?

What is the oxidation state in each element of COH2?
There are three elements, carbon, oxygen and hydrogen. Carbon's oxidation number is -4, each hydrogen is +1 and oxygen is +2.
What is the oxidation state of COH2?
In the molecule COH₂ (formaldehyde), the oxidation state of carbon (C) can be determined by considering the oxidation states of hydrogen (H) and oxygen (O). Hydrogen has an oxidation state of +1, and oxygen has an oxidation state of -2. Therefore, for the molecule COH₂, the oxidation state of carbon is calculated as follows: x + 2(+1) + (-2) = 0, which simplifies to x + 2 - 2 = 0, leading to x = 0. Thus, the oxidation state of carbon in COH₂ is 0.

What is the oxidation number of HClO?
For HClO oxidation No. is '0' . It is a neutrally charged molecule. However, The chlorine atom is in oxidation state (+1). How so???? you may ask . Using oxygen as that standard at '-2' , and hydrogen at '+1' We create a little sum +1 + Cl -2 = 0 ( overall charge on the molecule). Collecting terms Cl - 1 = 0 Cl = + 1 as required. NB When dissolved in water chlorine disproportionates. That is it simultaneously oxidises and reduces., Cl2(aq) = Cl^(+)(aq) + Cl^(-)(aq) It reacts with water molecules to form ;- Cl2 + H2O = HClO + HCl The supply of drinking water from public sources has chlorine bubbled through to act as a bacteriocide (kill the bugs). So tap/faucet water is a very weak solution of hydrochloric acid(HCl) and Hydrogen chlorate(bleach)(HClO). It won't harm you, because the solution is so weak, but just enough to kill the bugs.
