Some Useful Functions from stdlib.h
The header file “stdlib.h”, which stands for “standard library”, is a mixture of many different types of functions that are useful for day-to-day programming purposes. Unfortunately, not many learners are aware of the wealth of functions that lie here. Broadly, the functions in “stdlib.h” could be classified into five groups:
- Storage allocation
- Integer functions
- Text conversion
- Interacting with the environment
This appendix is an effort to introduce this collection of very useful functions to a new C programmer. This is not an attempt to demonstrate all the functions or all the uses of a particular function; rather, it emphasizes on how to use it in our own programs.
