C Programming Bit Field In this chapter you will learn the use of bit fields in C programs. Memory can be exploited using bit fields. Suppose, your program has some TRUE/FALSE variables which are categorized by structure variable and this structure variable is named status. For example: This structure variable will require 8 bytes of space in memory.

In this chapter you will learn about type casting. Type casting allows you to convert data from one type to another type. C type casting One data type can be converted to another data type through type casting. For type casting in C programming we use cast operator and it is expressed by (type). C type casting syntax
Since C programming has no direct support for error handling, but being a system programming language, it provides access to lower levels based on the return value. For any error, most C or even Unix function calls -1or NULLreturns errnoset as the error code. It is set as a global variable and indicates that an error has occurred
