Pick Random Element From Vector In C++

Bhushan Patil — Sun, 02 Jun 2024 16:04:31 +0000

In this tutorial, we will see how we can pick a random element from the vector in C++. Before moving further we should know what is vector. and how elements are stored, added, and removed elements in that vector. So we can say a vector is like a dynamic array. So with the help of […]

Memory Allocation in static data member in C++

Manan Gupta — Sun, 17 Mar 2024 13:39:59 +0000

In the language C++, we can create various data members using a class that is applicable to each object we create. The data members are initialized to their default value once an object of the class is created. Some of the things to know about static keyword is- If the data member of the class […]

C++ program to check if a number can be displayed using 7 segment LED

Saurabh Salunkhe — Fri, 16 Feb 2024 06:10:57 +0000

In this tutorial we are going to learn about the logic that will check if a number can be displayed using 7 segment LED in C++. We will also implement a C++ program that will demonstrate the above logic. What is a 7-segment display? The seven segment display consists of 7 LED lights arranged in […]

consteval specifier in C++

Vidhi Jain — Sat, 10 Feb 2024 05:07:47 +0000

Hello folks! Today, we will discuss consteval specifier in C++. Consteval specifier declares an immediate function to produce constant. This means that every potentially evaluated call should produce a compile-time constant expression directly or indirectly. The compiler evaluated the function at compile time.If while declaring a function or function template we use a consteval specifier, […]

Implement a Line Filter by Using Ranges in C++

Vidhi Jain — Sat, 10 Feb 2024 05:04:00 +0000

Let’s talk about filtering lines in C++. We can filter lines in the file by some characters present in it. Here, we use library Ranges for filtering the lines if certain words are present. For filtering, we need: split- This part of the program splits the text into lines filter- This filters the lines having […]

Find pascal triangle upto nth depth in C++

Swabhiman Mallick — Sat, 03 Feb 2024 13:15:34 +0000

Pascal’s triangle is a special arrangement of coefficients of the expansion of any binomial expression, such as (x+y)n . The binomial coefficients formed are written row-wise based on the values taken by n to form the triangular shape. The number of coefficients(or entries) in each line is one greater than the row number(same as the […]

Group multiple occurrences of array elements ordered by first occurrence in C++

Amit Raja Kalidindi — Fri, 02 Feb 2024 14:10:37 +0000

In this tutorial, we are going to learn how to group multiple occurrences of array elements in the order of the first occurrence of the elements in C++. Naive Solution: Let us assume that our array is A and its size is n. For storing the multiple occurrences of elements in groups we should maintain […]

How to remove specific elements from multiset in C++

Bhushan Patil — Mon, 22 Jan 2024 12:18:12 +0000

In this tutorial, we will see how to remove elements from multiset in C++. But first, we see what exactly multiset is and how it is similar to a set in STL. So multiset is an associative container in C++ that stores elements in a sorted manner but there is a slight difference between a […]

Calculate mean and standard deviation from a vector in C++

Bhushan Patil — Fri, 19 Jan 2024 11:28:55 +0000

In this tutorial, we will see how to calculate the mean and standard deviation from a vector in C++. We know that the mean has a formula which is the sum of elements divided by a total number of elements which is also called as total size of vector. Let’s see how to implement mean […]
