C Game Dev Color Struct
Here is a very basic Snake game in C, which I just want to make better. The game is working perfectly but it is very annoying because when playing it, it is always blinking. I hope that somebody could try it in their compiler to see how annoying it is.

- Sep 07, 2010 I decided a few days ago that i wanted to create a console-based version of that old game Snakes. The one where you're a little snake and you go around and eat orbs and get bigger and bigger, and the object of the game is to avoid yourself, as when you run into your body its game over. I've already ran into an issue.

A structure type (or struct type) is a value type that can encapsulate data and related functionality. You use the struct keyword to define a structure type:
Structure types have value semantics. That is, a variable of a structure type contains an instance of the type. By default, variable values are copied on assignment, passing an argument to a method, and returning a method result. In the case of a structure-type variable, an instance of the type is copied. For more information, see Value types.
Typically, you use structure types to design smallt modify the state of a struct. If you cannot declare the whole structure type as readonly, use the readonly modifier to mark the instance members that don't modify the state of the struct. In a readonly struct, every instance member is implicitly readonly.
Within a readonly instance member, you cannot assign to structure's instance fields. However, a readonly member can call a non-readonly member. In that case the compiler creates a copy of the structure instance and calls the non-readonly member on that copy. As a result, the original structure instance is not modified.
Typically, you apply the readonly modifier to the following kinds of instance members:
methods:
You can also apply the
readonlymodifier to methods that override methods declared in System.Object:properties and indexers:
If you need to apply the

The compiler declares a
getaccessor of an auto-implemented property asreadonly, regardless of presence of thereadonlymodifier in a property declaration.
You cannot apply the readonly modifier to static members of a structure type.
The compiler may make use of the readonly modifier for performance optimizations. For more information, see Write safe and efficient C# code.
Limitations with the design of a structure type
When you design a structure type, you have the same capabilities as with a class type, with the following exceptions:
You cannot declare a parameterless constructor. Every structure type already provides an implicit parameterless constructor that produces the default value of the type.
You cannot initialize an instance field or property at its declaration. However, you can initialize a static or const field or a static property at its declaration.
A constructor of a structure type must initialize all instance fields of the type.
A structure type cannot inherit from other class or structure type and it cannot be the base of a class. However, a structure type can implement interfaces.
You cannot declare a finalizer within a structure type.
Instantiation of a structure type
In C#, you must initialize a declared variable before it can be used. Because a structure-type variable cannot be null (unless it's a variable of a nullable value type), you must instantiate an instance of the corresponding type. There are several ways to do that.
Typically, you instantiate a structure type by calling an appropriate constructor with the new operator. Every structure type has at least one constructor. That's an implicit parameterless constructor, which produces the default value of the type. You can also use a default value expression to produce the default value of a type.
If all instance fields of a structure type are accessible, you can also instantiate it without the new operator. In that case you must initialize all instance fields before the first use of the instance. The following example shows how to do that:
In the case of the built-in value types, use the corresponding literals to specify a value of the type.
Passing structure-type variables by reference
When you pass a structure-type variable to a method as an argument or return a structure-type value from a method, the whole instance of a structure type is copied. That can affect the performance of your code in high-performance scenarios that involve large structure types. You can avoid value copying by passing a structure-type variable by reference. Use the ref, out, or in method parameter modifiers to indicate that an argument must be passed by reference. Use ref returns to return a method result by reference. For more information, see Write safe and efficient C# code.
Conversions
For any structure type, there exist boxing and unboxing conversions to and from the System.ValueType and System.Object types. There exist also boxing and unboxing conversions between a structure type and any interface that it implements.
