Function should Return true if 1’st employee greater then other wise

it should return flash declareTrue anf false int constant using enum

data type.

Algorithm:- Employee(object e2,e1)

This algorithm writes for comparing between two objects value.

Step1: create 2 objects of procedure1 e1,e2.

Step2: Scanning all detail of employee in both objects.

a) Read: e1.name, e1.salary, e1.age, e1.sex.

b) Read: e2.name, e2.salary, e2.age, e2.sex.

Step3: [Procedure2 calling] CALL: Set k:=agecheak(e1,e2)

Step4: Print: “1st employee oldest then 2nd

employee”

Step5: if (k==0) then

Step6: Print: “true”

Step7: else if (k==1) then

Step8: Print: “false”


Step9: Exit.

Procedure1:- STRUCTURE(name, salary, age, sex)

These procedures write for binding different data type in one block.

Step1:[initialize] name, salary, age, sex.

Step2: Exit.

Procedure2:- agecheak(object e1,object e2)

These procedures accept object type value. This algorithm wrires for

cheak the age of employee who is oldest?

Step1: [initialize] true:=0, false:=1.

Step1: if (e1.age>e2.age) then

Step2: return true.

Step3: else then return false.
