Two-dimensional arrays have rows and columns, storing data inside this matrix. These 2D matrices cannot be passed directly to functions like single-dimension arrays. The program needs to follow some required rules. Ways to Pass a 2D Array to function in C++ This article explains the various method to pass a 2D matrix to a method […]

In this post, we will see how to count decimal places in C++. Accuracy V/S Precision in Counting Decimal Places in C++ Programs A major challenge that comes with counting decimal places is that the program can either give a solution that is accurate or precise. An accurate solution is considered to be closest to […]

1. Introduction to the Problem Statement In C++ programming, checking whether a string is empty is a common and straightforward task but essential in many contexts, such as input validation, data processing, and conditional logic. Our Goal: To determine if a given string, such as "Hello" or "", is empty. Expected Output: A boolean value […]

This article explains the various ways to get filename from path using C++ programs. The examples will also describe ways to remove extensions as well if such needs arise. Get Filename From Path in C++ Finding a file name from its file path is a simple task. The program needs to find the last delimiter, […]

In this post, we will see how to escape percent sign in printf Method in C++. Escape percent sign in Printf Method in C++ printf() method uses percent sign(%) as prefix of format specifier. For example: To use number in prinf() method, we use %d, but what if you actually want to use percent sign […]

Learn about how to remove last element from Vector in C++. C++ provides a very useful data structure called vectors. These objects are similar to arrays in storing similar elements under a common name. However, they have a very useful additional feature. Vectors are dynamic in C++, which means that we can remove and add […]

C++ is an object-oriented language where we often interact with objects of different types. The object interaction becomes more interesting when we add runtime polymorphism to it. The runtime polymorphism, also known as, dynamic dispatch of methods, or method overriding means that a class can override the implementation of a method defined in the parent […]

In this post, we will see how to convert vector to Array in C++. Vectors and Arrays in C++ We can use an array to store a collection of data belonging to a primitive data type. It stores the data in a contiguous memory location. Vectors are very similar to arrays. We can assume vectors […]

1. Introduction In C++ programming, initializing an array within a constructor is a common practice, especially in object-oriented design. Consider a class named DataContainer that encapsulates an integer array. Our goal is to ensure this array is initialized appropriately when an object of the class is created. This article aims to guide beginners through various […]
