What does the `void` keyword specify in C?

The void keyword is utilized in C to denote that a function does not return any value to the calling function. When a function is declared with the void return type, it indicates to both the compiler and the programmer that the function, once executed, will not produce a value that can be used or assigned elsewhere. This is particularly useful for functions that perform actions rather than calculate and return results, such as printing to the console or modifying global variables.

For example, a function declared as void myFunction() clearly implies to anyone using or reading the function that they should not expect any return value to be used after calling myFunction(). This clarity helps in understanding the purpose and functionality of the function, thereby enhancing code readability and maintainability.

In contrast, the other options pertain to different concepts in C programming. The dynamic memory allocation pertains to functions like malloc or calloc and is not related to the void keyword. A constant integer value refers to constants defined using the const keyword or defined macro values, which again doesn't involve void. Lastly, while void* can be used to define a pointer type that can point to any data type, void by itself does not
