Sting Concatenatination is the process of creating a single string from multiple strings by combining them all together. In this article, we will discuss all approaches to concatenate multiple strings using C/C++ program. First of all, let's understand the problem statement. A set of C++ strings are ... Read More

Reversing a string means, moving first character to last, second character to second last and so on. In this article we will discuss how to reverse a string in place using C/C++ program. In the "in place" string reversing, we are not allowed take extra memory to store the string ... Read More

There are several inbuilt functions and objects to convert a number string to an integer in C++. Every method has its own advantages and disadvantages. In this article, we will discuss all the approaches to convert a number string to an integer in C++ with example code and use cases. ... Read More

In this article, we will discuss how to extract all the integers from a string using C++ program. We will explore all the possible approaches to do so. First of all, let's understand the problem statement. We have a string that contains a mix of digits and non-digits. ... Read More

To compare two strings in C++, we can use various inbuilt functions and approaches that are already discussed in the previous sections. However, there are some cases where we need to compare two strings case-insensitively, meaning that we need to ignore the case of the characters in the strings while ... Read More

A substring is a continues sequence of characters within a larger string. For example, the string "point" a substring of the string "TutorialsPoint". In this article, we will learn different approaches to check if a string contains a substring in C++. Here is a list of approaches for checking if ... Read More

Hexadecimal is a base 16 numbering system that uses 16 digits (from 0 to 9, and then A to F) to represent numbers. It is commonly used in computing systems to represent and store data. In this article, we will learn how to convert a normal integer to a hexadecimal ... Read More

C++ provides multiple ways to concatenate strings. Macro string concatenation is one of such way. In this article, we will learn how to use C++ preprocessor macros to concatenate strings and tokens. Understanding Macros in C++ In C++, macros are small pieces of code that are defined using the ... Read More

What is Linked List? A linked list is a linear data structure which can store a collection of "nodes" connected together via links i.e. pointers. Linked lists nodes are not stored at a contiguous location, rather they are linked using pointers to the different memory locations. A linked list can ... Read More

What is Adjacency List? An adjacency list is a collection of unordered lists that are used to represent a finite graph. Each list in the collection represents one of the vertex of the graph and it will store the adjacent vertices of that vertex. Let's see an example: ... Read More
