Software Engineering List of C Compilers (As early as 1973 and with the latest one at 2017) We have listed all major C compilers that has been in use. Some compilers were developed in 1980s (GNU GCC) while the recent ones are from 2017 (AOCC).
Software Engineering #if directive in C / C++ #if is a preprocessor directive in C to define conditional compilation. It can be used just like an if condition statement which impacts the compilation process
Software Engineering emplace_hint() in Set C++ STL emplace_hint() is a method of Set container in C++ STL to insert unique elements in a set at a desired position while maintaining the ascending order property of the set.
Software Engineering emplace() in Set C++ STL Emplace is a function of set container in C++ STL which is used to insert elements in the set. It is considered to be a faster alternative to insert().
Software Engineering Scanf and Printf in C Printf() and Scanf() are inbuilt library functions in C language that perform formatted input and formatted output functions. These functions are defined and declared in stdio.h header file.
Software Engineering Working with Navigator property of DOM In this article, we will look into navigator property of window object of a web document and use it to get information about the browser and load different code depending on browser.
Machine Learning (ML) KL Sum algorithm for text summarization Kullback-Lieber (KL) Sum algorithm for text summarization which focuses on minimization of summary vocabulary by checking the divergence from the input vocabulary.
Data Structures Interval Trees: One step beyond BST Interval tree is a variant of BST and is able to handle intervals in logarithmic time for search, insert and delete operations and is used in geometry.
Algorithms Split N into maximum composite numbers Given a number N, the problem is to count the maximum number of composite numbers that sum up to N. We solve this using a greedy algorithm in constant time
Algorithms Find point of 2D Line Intersection The point of intersection of two 2D lines can be calculated using two algorithms namely Elimination method and Determinant method which takes constant time O(1)
Software Engineering Different ways to initialize unordered_map in C++ In this article, we are going to learn about Unordered_map in C++ and specifically how to initialize them in our code in 4 different ways.
Algorithms Finding the number of sub matrices having sum divisible by K This article is about counting the number of sub-matrices such that the sum of the elements is divisible by k and using Dynamic Programming, we solve it in O(N^3)
Foo / Foobar in Computer Science Foo or Foobar in Computer Science/ Programming is a commonly used name for variables and functions. It has a history with MIT and DEC from 1959.
Machine Learning (ML) Image Recognition using Transfer Learning Approach In this post, we will explore Transfer Learning and see what exactly it is and how it works along with a Python implementation for the image recognition tasks.
Software Engineering Introduction to Lambda Expression in Java Lambda Expression is one of the newest features introduced in Java 8 release. It is an expression but in the form of an anonymous function definition.
Machine Learning (ML) LBPH algorithm for Face Recognition In this article, we will explore the Local Binary Patterns Histogram algorithm (LBPH) for face recognition. It is based on local binary operator and is one of the best performing texture descriptor.
Machine Learning (ML) Face Recognition using Fisherfaces In this article, we will explore FisherFaces techniques of Face Recognition. FisherFaces is an improvement over EigenFaces and uses Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA).
Software Engineering Swapping a queue in C++ STL In this article, we will explore examples of swapping queues. We can swap a queue in C++ STL in two ways using std::queue::swap and using std::swap.
Machine Learning (ML) Latent Semantic Analysis for text summarization Latent Semantic Analysis is an efficient technique for text summarization in order to abstract out the hidden context of the document.
Software Engineering #include in C #include is a preprocessor directive in C and C++ to include the code from other files (header files + C/ C++ code) in the current file.
Algorithms Number of ordered pairs such that (A[i] & A[j])=0 Given array A[] of n integers, find out the number of ordered pairs such that (A[i]&A[j])=0. This can be done using dynamic programming in O(N*(2^N)) time
Software Engineering Using Assert.h in C In this article we'll talk about one of those header files, namely the assert.h header file. First we'll look at the purpose of this file, second we'll go over code examples and in the third part we'll dive a little deeper into the details of this header file and tips on how to use it.
