Introduction 📃

In programming languages, we very often hear about the terms Strings and Characters. People used to get confused between strings and characters. But don’t worry, from now onwards, you will never be confused between these two terms. 

In this blog, we will briefly discuss about String, characters, and the difference between string and character.

Let’s move forward without any delay.

Character 🅰️

Characters are simple alphabets such as a, b, c, d...., but with one exception. Any single-digit integer, such as 0, 1, 2, 3, 4,..., and special characters, such as $,%, +, -,*,..., etc., are similarly treated as characters in computer programming, and you can assign them to a character type variable by simply enclosing them in single quotes.

Character

For example, we declare a character type variable ch and assign it the value 'a'.

char ch = 'a';


Here, 'a' is referred to as a character literal or a character constant, and 'ch' is a character type variable that can store a character from the implementation's character set. Not only  a, b, c, d...., etc., but also numbers like 0, 1, 2, 3, 4..., etc., or special characters like $,%, +, -,*..., etc. will be considered as character literals and can be assigned to a variable of character type, making the following point valid.

char ch = '$';


A character data type takes up 8 bits of memory; therefore, you can store any 256 possible values in a character whose ASCII value is between -127 and 127.

Any character, including special characters like !, @, #, $,%, &, *,_, +..., etc., can be stored in a character data type.

Note that only one letter or one digit can be enclosed in single quotations; multiple letters or numbers cannot be enclosed in single quotes. As a result, the following statements are incorrect in C/C++ programming:-

char ch = 'abc';

char ch = '123';

String 🔤

Strings are similar to sentences. They refer to a sequence of characters represented as a single data type. They're made up of a list of characters, which is actually an "array of characters." When passing information from the program to the user, strings come in quite handy. When storing data for the computer to use, they are less useful.

String

In C++, we can represent a string by declaring it using a string keyword or by making a character array.

Let’s see the following example to understand how to declare a string in C++:

/* String */
string str = "Ninjas";

/* Character Array */
char str[7] = ['N', 'i' ,'n' ,'j', 'a', 's', '\0']; 


Let’s learn the difference between string and character.

Frequently Asked Questions

What is a Character in programming?

character is a single letter, number, space, punctuation mark, or symbol that can be displayed on a computer.

What is a String in programming?

String refers to a range of characters.

How many letters can be enclosed in a character?

Only one letter or one digit can be enclosed in single quotations; multiple letters or numbers cannot be enclosed in single quotes.

How many possible ASCII values can be stored in a character?

A character data type takes up 8 bits of memory; therefore, you can store any 256 possible values in a character whose ASCII value is between -127 and 127.

What is the difference between an array and a string?

An array is a linear data structure that holds a collection of elements with the same data type. A string is a collection of characters defined as an object.
