In this tutorial, we will be discussing a program to understand iterator invalidation in C++.While iterating over the elements of a container object, sometimes it can become invalidated if we don’t apply bound checks. This mainly occurs due to the change in the shape and size of the container object.Example Live ... Read More

In this tutorial, we will be discussing a program to understand MakeFile in C++ and its applications.The task is to break the entire program with MakeFile. It is usually done by making .cpp files and .h files with all the classes/functionalities and link them together.Examplemain.cpp#include #include "function.h" using namespace ... Read More

In this tutorial, we will be discussing a program to understand Kruskal’s minimum spanning tree using STL in C++.For this, we will be provided with a connected, undirected and weighted graph. Our task is to calculate the Minimum spanning tree for the given graph.Example Live Demo#include using namespace std; typedef pair ... Read More

In this tutorial, we will be discussing a program to understand the lower bound in C++.lower_bound() method in C++ is used to return the very first number in the container object which is not less than the given value.Example Live Demo#include int main(){    std::vector v{ 10, 20, 30, 40, ... Read More

In this tutorial, we will be discussing a program to understand how to read the alternate nth byte and write it in another file.For this, we will be provided with two .txt files. Our task is to write the contents from one file to another file using Iseek() which is ... Read More

In this tutorial, we will be discussing a program to understand the internal details of std::sort() in C++.std::sort() function is used to sort down an array using a comparison of the elements. If we look at the in-depth functionality of std::sort() it uses IntroSort algorithm to sort the elements of ... Read More

In this tutorial, we will be discussing a program to understand INT_MAX and INT_MIN in C/C++.INT_MIN and INT_MAX are macros that are defined to set the minimum and maximum value for a variable/element.Example Live Demo#include int main(){    printf("%d", INT_MAX);    printf("%d", INT_MIN);    return 0; }Output2147483647 -2147483648ApplicationCalculating MIN value in ...

In this tutorial, we will be discussing a program to understand integer literal in C/C++ (Prefixes and suffixes).Integer literals are literals for integer values directly represented in the source code. Further, they are of two types −Prefixes − Prefixes denotes the base of the value. For example, 0x10 indicates hexadecimal ... Read More

In this tutorial, we will be discussing a program to understand the insertion sort using C++ STL.In this we use std::upper_bound to find the element at the wrong position, then rotate the unsorted part of the array to make it sorted.Example Live Demo#include //function to perform insertion sort void insertionSort(std::vector ... Read More

In this tutorial, we will be discussing a program to understand the insertion and deletion in STL set in C++.The set is a container element. The properties that make it unique is that it can only contain unique elements and they can be looped over in a sorted manner.ExampleInsertion Live Demo#include ... Read More
