output 1 :
 1 arthemetic operater
 2 modulo operater
 3 relational operater
 4 logical operater
 select an option :1
enter the value of a and b is :2
67
the value of a+b is : 69

output 2:
 1 arthemetic operater
 2 modulo operater
 3 relational operater
 4 logical operater
 select an option :2
enter the value of a and b is :2
5
the value of ab is : 2

output 3:
 1 arthemetic operater
 2 modulo operater
 3 relational operater
 4 logical operater
 select an option :3
two no. is a and b is 23
45

 max. = 45
 min. = 23     

output 4:
 1 arthemetic operater
 2 modulo operater
 3 relational operater
 4 logical operater
 select an option :4
enter any character s

it is consonent
