software engineering push() in Stack C++ STL We have discussed about how we can insert elements in stack container using push() method provided by C++ STL(Standard Template Library).
software engineering Add strings in C++ There are multiple ways to add two or more strings or a string and an integer in C++. We will explore each method is depth but the easiest approach is to use + operator and the format() method in C++20.
software engineering Sorting a vector in C++ A vector in C++ can be sorted in multiple ways like ascending or descending order, using a custom comparison function, using lambda, sorting a 2D matrix and using nth_element() function.
software engineering Understand use of Pointers (*) in C and C++ A pointer in C and C++ is a variable that contains a memory address which is usually the address/ location of another variable in the memory.
software engineering Get length of array in C and C++ In C and C++, we find the length of an array we need to use the sizeof operator and get the length as size of entire array divided by size of an element.
software engineering Hashing in C++ using std::hash In this article, we will cover how hashing is natively supported in C++ through STL (std:hash) and how we can use it to generate hash of any object in C++.
software engineering How to ban use of some functions in C and C++? The approach to prevent the use of functions is to replace the function definition (using macros) with a dummy definition with a message that the function is banned from use.
software engineering Introduction to Make and Makefile We have explained the concepts behind Make tool and Makefile which forms the basics of compiling and building executable for a C/ C++ project codebase.
software engineering Map vs Multimap in C++ STL The only difference between map and multimap in C++ is that map can only store unique key-value pairs while is multimap, no key value pair is unique.
software engineering equal_range() in Set C++ STL equal_range() is a built in function for Set container in C++ STL which is used to determine the range of a number or key value passed as a parameter.
software engineering Bucket in Unordered map in C++ STL unordered_map::bucket for unordered map container in C++ STL is used to check if 2 elements have the same hash and hence, falls into the same bucket.
software engineering Relational Operators for comparing Queue in C++ STL Relational Operators used with queue c++ STL are overloaded operators which are used to perform appropriate comparisons between two queue objects. The queues are compared element by element.
software engineering Swap two sets (set::swap) in C++ STL In this article, we will take a look into swapping two set containers in C++ Standard Template Library using swap method.
software engineering gets() vs fgets() in C and C++ gets() and fgets() are functions in C language to take input of string with spaces in between characters. gets suffer from buffer overflow which is solved by fgets
software engineering Different ways to remove elements from vector in C++ STL In this article, we will go through multiple ways to delete elements from a vector container in C++ STL like pop_back, pop_front, erase, clear, remove and more
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 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.
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.
software engineering Getting started with 2D graphics in C++ (SDL2) We will start by implementing a basic class design which initialize various parameters of SDL with a clear black window. From there, we will implement drawing different shapes and then we will create a simple animation
software engineering Different ways to copy a vector in C++ In this article, we will explore different methods to copy a vector in C++ and all covered methods use deep copy that the memory address of new copy is different from the original vector.
software engineering set::rbegin() and set::rend() in C++ STL In this article, we will explore the rbegin and rend function of set container in C++ STL and use examples to demonstrate different use cases like reverse traversal
software engineering set::begin and set::end in C++ STL In this article, we will explore the begin and end function of set container in C++ STL and use examples to demonstrate different use cases.
software engineering Type Casting in C++ Learn about type casting in C++ where data types can be converted automatically by compiler, explicitly converted by user and by using the cast operator.
