2, Function declaration: you can declare functions in the header file, so that these functions can be used in other source files, without worrying about the specific implementation of the function. This practice facilitates modularity of code, allowing programmers to focus on writing code for ...
The keywordvoidhas three uses: to specify a function return type, to specify an argument-type list for a function that takes no arguments, and to specify a pointer to an unspecified type. You can use thevoidtype to declare functions that return no value or to declare a pointer to an uns...

The function is the fundamental modular unit in C. A function is usually designed to perform a specific task, and its name often reflects that task. A function contains declarations and statements. This section describes how to declare, define, and call C functions. Other topics discussed are:...
