int main()
{
enum value{VAL1=0, VAL2, VAL3, VAL4, VAL5} var;
printf("%d\n", sizeof(var));
return 0;
}

Thanks to rohit.

In C enum is internally treated as Integer.Hence size of enum will be size of an integer (ie)2 bytes(visual C or turbo C) or 4 bytes(GCC compiler Linux) depending upon the compiler.

Enum is keyword to define named integer constants in 16-bit compiler. The integer value take 2bytes to store the value and for GCC 4 bytes to store it. The variable can store only integer value you can answer. And if you want to initialize, initialize at part of declaration at any cost.

But there are 5 integer (VAL1=0, VAL2, VAL3, VAL4, VAL5)
So sizeof(var) will be 10 byte........
Please explain me?

@ Ramakant
there is no issue of how many variable/elements are in enum.
so that Pallavi is right.
thanks Pallavi

"sizeof () " operator returns the actual size of a data type.
For ex: sizeof (float) ; returns 4 bytes.
Here enum treated as integer data type hence returns 2bytes.

Value inside enum is not properly arranged then how the answer came 2. It is my doubt only.

The value assigned to the 1st variable is 0 so it's integer, enum also continues its values as integers so in 16 bit compiler integer value is 2.

Hi guys. Initial value i.e. val1=0, remaining enumeration constants by default incremented by 1 then. At a time it (var) contains only one enumeration constant. So that answer is 2 (in 16-bit platform).
I hope you understand.

After enum(...) var-why we are writing it here???
whats its actual meaning is??
what it signifies??
