The major difference between types of parsing techniques top-down and bottom-up parsing is that the top-down parsing follows method to construct a parse tree for an input string which begins at the root and grow towards the leaves. As against, in bottom-up parsing, a reverse method where the parsing starts from the leaves and directed towards the leaves. Before understanding the types of parsing, we must know what is parsing and why it's done. Parsing is the technique of examining a text … [Read more...]

High-level language and low-level language are the types of programming languages. The prior difference between high level and low-level language is that the high-level language is easily interpreted by programmers but not machines whereas low-level language can be easily understood by machines but not by humans. The low-level language contains machine language and assembly language. Content: High-Level language and Low-Level language Comparison Chart Definition Key … [Read more...]

An algorithm is a sequence of steps which is utilized in order to solve a computational problem whereas pseudocode is nothing but a more simple form of an algorithm which involves some part of natural language to enhance the understandability of the high-level programming constructs or for making it more human-friendly. Computer programming contains an enormous part, of generating unambiguous, sequence-wise procedures for the computer to follow in order to produce particular results. … [Read more...]

The Flood-fill and boundary-fill algorithm come under the category of area filling algorithm. The crucial differing point in these algorithms is that the flood-fill first checks whether a random pixel is having the region's original colour or not. Conversely, the boundary-fill examines for boundary pixel and it has already been filled or not. Area or region filling is a process of colouring a specific image area or region. These areas can be described based on the pixels or geometric … [Read more...]

While drawing a line on computers they need to perform a set of computation, and it is not that simple as humans can do it in a simple way. So, in computer graphics, there are two algorithms used for drawing a line over the screen that is DDA (Digital Differential Analyser) algorithm and Bresenham algorithm. The chief difference between them is that the DDA algorithm uses floating point values while Bresenham employs integer with round off functions. Furthermore, the implementation of the DDA … [Read more...]

C# and C++ are the programming languages where the C++ is the descendant of the C#. However, C# is derived from C language and it has many features of C and C++, but some features are also dropped in the C#. When it comes to programmer's productivity the C# is miles ahead from C++ and C. The major difference between the C# and C++ lies within its applications where the C# can be used to develop web as well as business applications whereas C++ is useful when the programmer wants to create … [Read more...]

In programming, the solution to a problem is first elucidated in the form of the algorithm which contains sequential steps for the solution. For the programmer convenience, the two forms are evolved to express the algorithm that is Flowchart and Pseudocode. A flowchart is constructed with the help of various symbols and provides more understandability to the algorithm. The algorithm and flowchart are the two sides of the same coin and dependent terms. Creating an algorithm is a very crucial … [Read more...]

The data structure can be defined as the interpretation of logical relationship existing between the solitary elements of data. The linear and non-linear data structure is the subclassification of the data structure which comes under the Non-primitive data structure. The crucial difference between them is that the linear data structure arranges the data into a sequence and follow some sort of order. Whereas, the non-linear data structure does not organize the data in a sequential manner. The … [Read more...]

Definition and Declaration are very confusing terms if you are new to programming. The two concepts are different in some ways as the definition involve memory assignment to the variables while in declaration memory is not allocated. The declaration can be done more than one time, conversely, an entity can be defined exactly once in a program. The definition is automatically a declaration in most of the scenario. Now let's understand the difference between definition and declaration with the … [Read more...]

Insertion sort and selection sort are the techniques used to sort the data. Majorly insertion sort and selection sort can be differentiated by the method they use to sort the data. The insertion sort inserts the values in a presorted file to sort a set of values. On the other hand, the selection sort finds the minimum number from the list and sort it in some order. Sorting is a basic operation in which the elements of an array is arranged in some specific order to enhance its searchability. … [Read more...]
