In this tutorial, we will learn how to obtain user input and store it in a vector in CPP. It will ask the user the number of elements they want to store and then the elements. The elements the user enters will be stored in a vector, which acts like a ‘dynamic- array’ that can …
Why are we studying this topic? Nowadays everyone is busy doing competitive programming and you know that when there is a large number of test-cases, code takes more time to perform the input/output operation and we all know that in competitive programming execution time should be as small as much as possible. So to minimize …

In C++, reversing a vector is a common task that can be achieved in various ways. A vector is a dynamic array that can shrink or grow in size as elements are removed or added. This blog post will explore different methods to reverse a vector in C++. We will also provide a step-by-step guide …
Hello everyone In this tutorial we will understand how to solve the problem of removing all the unique elements from an array by means of c++ For this we will use concepts like count the frequency of each element ,identifying unique elements and removing unique elements . So lets get started but before lets understand …

In this article, we will see how you can merge two arrays in C++. The array is a collection of similar types of data items in a larger group. The array is used to store multiple similar types of values in a single variable. Code: In the below code, we will see how we can …
The cos() function in C++ computes the cosine value of a given angle in radians. This mathematical function is part of the C++ Standard Library and resides in the <cmath> header. This blog post will delve into the details of the cos() function, including its syntax, usage, and an example to illustrate its application. Understanding …
In this blog, we will explore two essential memory allocation features in C++: ‘new’ and ‘malloc’. Dynamic memory allocation plays a crucial role in programming and requires developers to consider it carefully. Developers often face multiple solutions for a given problem, requiring us to select the most optimal approach. Achieving optimization relies on efficient memory …
The std::string::compare() function in C++ is used to compare two strings lexicographically. It is a member function of the std::string class defined in the <string> header. The function returns an integer value that indicates the relationship between the two strings being compared. Syntax: int compare(const string& str) const; int compare(const char* s) const; int compare(size_t …
