In C programming language, a struct is like a special container that can hold a bunch of related information. It's like a Lego house that has different Lego pieces inside, with each piece representing a different part of the house.
A struct can have different parts, like a name, an age, and a favorite color. These parts are called "members" or "fields". For example, you can create a struct called "Person" and it can have members like "name", "age", and "favoriteColor".
When you create a struct, you need to tell the computer what kind of information it will hold. This is done by "declaring" the struct, which is like telling the computer what kind of Lego house you want to build.
Once you have declared the struct, you can use it to store information. You can also access the information stored in a struct by using the "." symbol followed by the member name. For example, if you want to access the age of a person in the "Person" struct, you would use "person.age".
Structs are especially useful when you want to store a bunch of related pieces of information together, like when you're working with databases or creating complex programs. They can help keep your code organized and make it easier to access and manipulate the data you're working with.
