Substring for Dummies
noun
What does Substring really mean?
Substring is a term that is often used in the world of computer programming and coding. It might sound intimidating, but let me break it down for you in a way that I hope will make it easier to understand.
Imagine you have a long piece of string, like the one you might use to tie a package. Now, let's say you only want a small piece of that string, not the entire length. You would simply cut out or extract the specific part that you need, right? Well, in programming, a substring is similar to that concept of cutting out a smaller portion of a long string.
In more technical terms, a substring refers to a sequence of characters within a longer string. It can be any set of characters, whether it's just a single letter, a whole word, or even a phrase. The key point here is that the substring is always a part of a larger string, just like the small piece of string you cut out from the longer one.
To fully understand this, let me give you an example. Imagine you have a sentence, like "I love ice cream!" The entire sentence is like the long string. Now, let's say you only want the word "ice" from that sentence. You can substring this word by cutting out those specific three letters from the longer string. So, in this case, the substring would be "ice."
Now, here comes the interesting part. The term substring can also refer to removing or deleting a specific sequence of characters from a string. It's like erasing or removing a part of the string that you don't want anymore, just like crossing out a word from a sentence.
To explain this, let's continue with our previous example. Imagine you have that same sentence "I love ice cream!" and this time you want to remove the word "love" from it. By deleting or erasing this specific section of the string, you are substringing it. So, in this case, the process of substringing means you will end up with the sentence "I ice cream!"
In summary, think of substring as cutting out or extracting a specific part of a larger string, like getting a small piece of string from a longer one. It can also mean removing or deleting a particular portion of a string, just like crossing out words from a sentence.

Substring In a sentece
Learn how to use Substring inside a sentece
- When you take a big piece of cake and cut a smaller piece from it, the smaller piece is called a substring.
- If you have a long word like 'elephant' and you only take the first 3 letters 'ele', 'ele' becomes a substring of the word 'elephant'.
- In a sentence like 'I love ice cream', if you take the word 'ice' out, 'ice' becomes a substring of the sentence.
- If you have the number 987654, and you only take the last 3 digits '654', '654' can be considered as a substring of the original number.
- When you have a long string of letters like 'abcdefgh', and you take a small part like 'def', 'def' becomes a substring of the original string.
