Answer:
C. 4
Step-by-step 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.
