String Definition: What It Means In The World Of Computer Programming

 



react to section with thumbs-down

If you are a budding programmer or if you are appearing for an interview, it is essential for you to brush up on your programming basics at regular intervals.

One such fundamental concept is String. A string in programming is a collection of characters, either as a variable or a literal constant.

The concept of string may seem easy, but performing operations on any String can be a bit tricky. Therefore, you should revise your basics frequently and practice various string operations like the subsequence of a string, a palindrome of a string, or the longest palindromic subsequence of a string.

In this post, we are going to talk about what Strings mean in programming and what all you need to know about it.


What Does String Mean In Programming

A string is an array of characters. It contains letters, symbols, and numbers. All these elements are stored in an array in a sequence.

In most programming languages, strings are denoted by a quotation mark. No matter what type of elements a string contains, it will always be stored in the form of text in the system.

For better understanding, consider the following example:

If you have initialized any variable with a value of 5, it will be considered an integer value by your system. However, in case you have initialized it as “5”, the system will automatically pick it up as a character. You can not use such value in any calculations.

Another thing that you need to know about strings is that they are stored in a sequence. So, if you have stored a string as “I love programming”, it will be stored in the same way. for instance, if you find a string with programming love, you will not find any results.

Strings are also used by many websites to store user credentials like passwords, usernames, and content on the website.


Characteristics Of A String

Here are some characteristics of string in programming that you need to know before writing a program on the same.


Sequence Of Characters

A string is simply a sequence of characters that include numbers, letters, and symbols. You can also define a string where there are only numbers or combinations of two or more types of characters.


Empty Strings

As the name suggests, an empty string is a string with no values. You can easily initialize a string by keeping the quotation marks empty.

Also, you must know that an empty string and space are different. Space itself is a character and occupies the length of one.


Length Of String

To count the length of a string, you can simply count the characters in the string. Although most programming languages have an in-built function to count the length of a string, you can still count the characters to know the length of a particular string.


String Case

A string can be written in different cases. For example, the whole string can be written in UPPERCASE, lowercase, Sentence case, and Capital Case.

Aggressive cow problem is a tough nut to crack in programming as well as your real life!! This is one of the most advanced problems related to the application of binary search. The aggressive cow question is therefore generally every interviewer’s favorite. This is because to solve this problem, you need to know the basic application and concept of binary search. But how do you actually resolve the  aggressive cows problem ? Well, the answer is obvious: Using Binary Search!! Still not sure how to find the solution? Stick to this post to learn.  Here is everything you need to know about the  aggressive cows  problem and its solution.    The Problem Statement Before understanding the solution to the problem, let’s first understand the problem statement. The problem statement goes like this: John, the farmer, has constructed a new barn consisting of N stalls. He has built all these stalls in a single line X. In his barn, he has a C number of cows. His cow...

Advantages and Limitations of Using Recursion in Programming

Image
Recursion is a popular programming technique that allows functions to call themselves to solve a problem. It is widely used in many programming languages and has its advantages and limitations. In this essay, we will explore both the advantages and limitations of using recursion in programming. Recursion is a powerful programming technique that involves a function calling itself until a certain condition is met. There are several advantages of using recursion in programming: Simplifies complex problems: Recursion is often used to simplify complex problems by breaking them down into smaller, more manageable sub-problems. This makes it easier to understand and solve the problem at hand. Reduces code complexity: Recursive functions can be used to write elegant and concise code by reducing the need for repetitive code blocks. Recursive solutions can often be shorter and more concise than iterative types of sorting . Easy to read and understand: Recursive solutions can be very easy to re...

Python is a much-appreciated general-purpose programming language. It is utilized in various industries, including web development, machine learning, and desktop applications.  Luckily, the language Python has an easy-to-use syntax suitable for beginners. This makes Python an excellent language for novices to learn.  In this blog article, all of Python's fundamental concepts will be covered. You will feel confident using a  Python online compiler  to create projects. Let’s get started! About Python Python is one of the most used programming languages in modern-day, created by Guido van Rossum and released to the public in 1991. The public has free access to the source code for Python using a Python online compiler, and there are no restrictions on how it may be used or distributed, including for profit.  Practically anything may be produced with it for web development, including online web apps, mobile applications, tools, machine learning, data analytics, and m...
