string meaning

A string is a sequence of characters, such as a word or sentence. In most programming languages, strings are data types that can be used to store and manipulate text.

They are commonly used in computer programs to store textual information. You can think of strings as containers for characters (e.g., letters and words).

That said, there are different kinds of strings that appear in almost any programming language: single-quoted strings, double-quoted strings and delimited strings also known as raw strings.

Single-quoted strings – string meaning

A single-quoted string is delimited by ‘ and ‘ symbols. They are commonly used in programming when you want to print text.

To understand single-quoted strings, let’s look at an example: In the above example, we are creating a variable named “name” and assigning a string with the value “Mark”.

You can use single-quoted strings to assign values to variables or to display text. For example, to display the name “Mark” on the screen, you can write a line of code like this:

That is, you use the name of the variable followed by the “as” operator and then the text you want to display.

Single-quoted strings are great when you want to display text as it is. If you want to display text with special characters, such as a mathematical expression, you may need to use another type of string instead.

Double-quoted strings – string meaning

A double-quoted string is delimited by “ and “ symbols. Unlike the single-quoted string, the double-quoted string can display text with special characters.

This is because it is processed by the compiler before it is displayed on the screen. Double-quoted strings are commonly used when you want to display text with special characters.

For example, to display the name “Mark” followed by a mathematical expression, you can write a line of code like this: That is, you use the name of the variable followed by the “as” operator and then the text you want to display.

Unlike the single-quoted string, the double-quoted string allows you to use special characters, such as mathematical symbols. Double-quoted strings are great when you want to display text with special characters.

However, one thing to keep in mind is that the compiler processes them before they are displayed on the screen.

This means that if you want to display a word that has a special character, you have to escape the special character first.

For example, if you want to display the word “Mark” with a dollar sign, you have to escape the dollar sign like this: “$Mark”.

Delimited strings (raw strings) – string meaning

A delimited string is commonly referred to as a raw string. In most programming languages, the raw string is a hybrid between the single-quoted and double-quoted string.

That said, it has most features of the double-quoted string, but without being processed by the compiler. Raw strings are useful when you want to display text with special characters, but you want to avoid escaping them.

For example, to display the name “Mark” followed by a mathematical expression, you can write a line of code like this: That is, you use the name of the variable followed by the “as” operator and then the text you want to display.

Unlike the double-quoted string, the delimited string allows you to use special characters without escaping them. That said, there is a catch here. Unlike the double-quoted string, the raw string is not processed by the compiler.

This means that if you want to display a word that has a special character, you don’t have to escape the special character.

For example, if you want to display the word “Mark” with a dollar sign, you don’t have to escape the dollar sign like this: “$Mark”. This is because the raw string is not processed by the compiler.

Differences between single and double quoted strings – string meaning

As you have seen, single-quoted strings are used to display text as it is, whereas double-quoted strings are used to display text with special characters.

However, there are differences between the two that you should be aware of. Raw strings are not processed by the compiler, whereas double-quoted strings are.

This means that if you have a word in a single-quoted string that has a special character, you don’t have to escape the special character, whereas if you have a word in a double-quoted string that has a special character, you have to escape the special character.

Conclusion

As you can see, there are different types of strings that you can use in your code, such as single-quoted strings, double-quoted strings and delimited strings.

However, each type of string has its own purpose and can be used in different scenarios. It is important to understand the different types of strings and when to use them.

Only then will you be able to write code that is efficient and easy to read.
