`typedef` is a keyword in the C programming language used to create a new data type. It allows you to define a new name for an existing data type. The syntax for the `typedef` statement is as follows:
```c
typedef existing_data_type new_data_type;
```
Here, `existing_data_type` represents the data type you want to create an alias for, and `new_data_type` is the new name you want to give to that data type.
For example, let's say you want to create an alias for the `int` data type called `myInt`. You can use the `typedef` statement as follows:
```c
typedef int myInt;
```
After this declaration, you can use `myInt` as a synonym for `int` throughout your code. It can be useful to make your code more readable and maintainable, especially when dealing with complex data structures or function pointers.
