Imagine you have a bunch of toys that you want to put together to make something new, like a robot. But the different toys are made by different companies and are not meant to work together.
This is where glue code comes in. Think of it like glue that can stick different parts of the toys together even though they weren't made to work together.
In software terms, glue code is like a special code that helps different software programs work together even if they weren't originally designed to. It's kind of like a translator that helps different programs understand each other's language so they can work together smoothly.
For example, if you wanted to make a website that used both Google Maps and Amazon's payment system, you would need some glue code to make them work together. The glue code would help the website send information from Google Maps to Amazon's payment system and back again so everything works smoothly.
Overall, glue code is a really important tool that helps different software programs work together. It's like the glue that holds everything in your toy robot together and makes it work the way you want it to.
