Write a program to create menu for following operators : a. Arithmetic operator b. Modulo operator c. Relational operator d. Logical operator (switch case)

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
