Here the table is divided into two parts, the upper part shows the conditions and the lower part shows what actions are taken. Each column of the table is a rule.

Similarly, the actions taken for other conditions can be inferred from the table. FORMAL SYSTEM SPECIFICATION 28 Software Engineering Keerthana P, Manasa KN, Ganga D Bengal
