Certainly! In the realm of C programming, the typedef keyword is a powerful tool used to create aliases or alternate names for existing data types. This allows programmers to define custom names for data types, making the code more readable and easier to maintain.

For instance, consider the following example:

c
typedef int marks; // 'marks' is now an alias for the 'int' data type int main() { marks mathMarks = 95; // 'mathMarks' is of type 'int', as 'marks' is an alias for 'int' printf("Mathematics marks: %d\n", mathMarks); return 0; }

In the code above, typedef is used to create an alias marks for the int data type. This allows us to use marks instead of int when declaring variables, which can make the code more descriptive and easier to understand.

The C typedef keyword is used to redefine the name of already existing data types. When names of datatypes become difficult to use in programs, typedef is used with user-defined datatypes, which behave similarly to defining an alias for commands.
