Void contract: An agreement to carry out an illegal act is an example of a void agreement.

A void agreement is void ab initio, i e from the beginning while a voidable contract can be voidable by one or all of the parties.  A voidable contract is not void ab initio, rather, it becomes void later due to some changes in condition.  In sum, there is no scope of any discretion on the part of the contracting parties in a void contract.  The contracting parties do not have the power to make a void contract enforceable.
