Tha major difference between an agreement and a contract is that an agreement can be verbal buta contract is always written and signed by the parties.

Thanks ketaki Kumar.. But how to distinguish in the various cases of question.. What is the main difference?

In case of void agreement,it is void from the beginning but in case of void contract,it is valid at the beginning(when it is made) but later by some supervening impossibility or because of govt passing rule that sth has to be not done etc,it becomes void.in case of void agreement, it is void -ab-initio
