C#.NET enums with explicit and implicit values: what integers are printed? enum color : int { red, green, blue = 5, cyan, magenta = 10, yellow } Console.Write((int)color.green + ", "); Console.Write((int)color.yellow);

Introduction / Context:
This item checks your knowledge of how C#.NET assigns underlying integer values to enum members when some are explicit and others are implicit.

Given Data / Assumptions:

• red and green have no explicit values.
• blue = 5 is explicit.
• cyan follows blue without an explicit value.
• magenta = 10 is explicit, followed by yellow with no explicit value.

Concept / Approach:
Rules: the first unassigned enum member gets value 0; each subsequent unassigned member increases by 1 from the previous member’s value. When an explicit value appears, counting resumes from that value for subsequent unassigned members.

Step-by-Step Solution:

Verification / Alternative check:
Print all values via foreach (var x in Enum.GetValues(typeof(color))) Console.Write((int)x + " ");.

Why Other Options Are Wrong:
2, 11 and 2, 6 mis-assign the early implicit values. 1, 5 uses yellow as 5, ignoring the explicit magenta = 10.

Common Pitfalls:
Assuming implicit values reset after each explicit assignment or always start at 0 for each block; they continue from the last explicit value.
