enum result s1,s2;

s1=pass; s2=fail;

printf("%d",s1); }

• error

• pass

• fail

• 0

#include <stdio.h>

enum example {a = 1, b, c};

enum example example1 = 2;

enum example answer()

{ return example1; }  

int main()

{

(answer() == a)? printf("yes"): printf("no"); return 0; }

• yes

• no

• 2

• error

#include<stdio.h>

#define MAX 4

enum s1 { a,b=3,c };

main()

{ if(MAX!=c)

printtf("hello");

else printf("welcome"); }

• error

• hello

• welcome

• 2

Arithmetic operations such as addition, subtraction, multiplication and division are allowed on enumerated constants.

• true

• false

#include<stdio.h>

enum sum

{

a=1,b,c,d,e

};

int main()

{ printf("%d",b*c+e-d); }

• error

• 7

• 2

• 4

#include<stdio.h>

enum test

{ a,b,c=5 };

int main()

{ enum test s;

b=10;

printf("%d",b); }

• error

• 10

• 1

• 4

What is the similarity between a structure, union and enumeration?

• All of them let you define new pointers

• All of them let you define new structures

The keyword __________ is used to declare new enumeration types in C

• struct

• enum

• int

The enum in C is _______

• built-in data type

• legal data type

• user-defined data type

• function defined type

how enum differ from macro?
