Which of the following is not user defined data type?
1 : 
struct book
{
    char name[10];
    float price;
    int pages;
};
2 : 
long int l = 2.35;
3 : 
enum day {Sun, Mon, Tue, Wed};
1
2
3
Both 1 and 2
Answer: Option
Explanation:

C data types classification are

  1. Primary data types
    1. int
    2. char
    3. float
    4. double
    5. void
  2. Secondary data types (or) User-defined data type
    1. Array
    2. Pointer
    3. Structure
    4. Union
    5. Enum

So, clearly long int l = 2.35; is not User-defined data type.
(i.e.long int l = 2.35; is the answer.)
