Give the differences between library functions and user-defined functions.

Give the differences between library functions and user-defined functions.

Library functions: 

1. Some of the operations are programmed and stored in C library so that they can be called in the program. These functions are called as library functions.

2. Library functions are in-built functions.

User-defined functions:

1. Large programs can be broken down into smaller sub programs or modules. These sub programs are called user-defined functions.

2. User-defined functions are created by the user.
