Answer 1

Answer:

C. 4

Explanation:

typedef enum{

       red,orange,yellow,green,blue

}

color_t;

defines an enumeration type color_t with the values red,orange,yellow,green,blue.

If we print out the values of these individual elements they will be as follows:

red : 0

orange : 1

yellow: 2

green: 3

blue: 4

Note that the integer values are dependent on the position in the definition.
