**Hungarian Notation: -** The word starts with a lower case prefix and the [**rest of the word**](https://www.mindstick.com/forum/95355/how-does-a-selection-sort-work-for-an-array) is in the Pascal case. It comes in two forms.

The first one is in **system Hungarian** where prefix indicates data types of variable.

For example: - strStudentName. In this str represents string.

The second one is **apps Hungarian** which indicates a logical purpose.

For example- the row position.

#### Another Definition

Where the Hungarian notation is a [**naming convention**](https://www.mindstick.com/forum/145554/why-should-we-have-to-use-a-naming-convention-and-what-are-its-advantages) in computer programming that indicates either the type of object or the way it should be used.

That was originally proposed by Charles Simonyi, a programmer at Xerox PARC in the early 1980s.

These are two variations of Hungarian notation: Systems and Apps.

These both involve using a special prefix as part of the name to indicate an object's nature.

#### Hungarian notation prefixes

- b for boolean
- ch for char
- w for word
- dw for double word
- i for integer
- f or fp for floating-point
- d or db for double-precision floating point
- p for pointer
- u32 for unsigned 32-bit integer
- fn for function
