NET Framework Garbage Collector
.NET Framework > Garbage Collector
The .NET Framework garbage collector manages the allocation and release of memory for applications.
When you create a new object the CLR allocates memory for the object in a managed heap.
The runtime continues to allocate space for new objects.
Because the memory is not infinite the garbage collector performs a collection in order to free some memory.
Advantages:

Because the memory is not infinite the garbage collector performs a collection in order to free some memory.
Advantages:
- don't have to free memory
- effectively allocate objects on the managed heap
- clears memory of the objects no longer being used
- memory safety

Float type in C#
C# > Types > Float
Float is a simple type that stores 32-bit floating-point values.
By default, a float on the right side of the assignment operator is treated as double.
If you do not use the suffix F, you will get a compilation error because you are trying to store a double value into a float variable:
float x = 7.5; // Error Literal of type double cannot be implicitly converted to type 'float'; use an 'F' suffix to create a literal of this type
To initialize a float variable, use the suffix f or F:
float x = 7.5F; // Ok

Char type in C #
Types in C# > Char
Char type in C# declares a Unicode character.
Unicode characters are 16-bit characters that are used to represent most of the known written languages throughout the world.
Example of char:
1.
char[] chs = new char[2];
chs[0] = 'U'; // Character literal
chs[1] = (char)85; // Cast from integral type
foreach (char c in chs)
MessageBox.Show(c.ToString());
2. Null Char
