Question

Briefly, in your own words, describe the purpose of each of the header (*.h) files. Set a breakpoint at the no_swap () function and observe the variables a and b. Single step through the function and observe the behavior. Next, repeat with the swap () function. Comment on the differences between the two functions and explain the reasons for the difference in behavior. Lastly, move the first two lines of the while (1) loop where the variables a and b are initialized, outside of the loop so they appear right after the Cerebot mx7ck setup () function call. Using the debugger, determine the values of a, b, c, and d after the body of the while (1) loop has been executed four times.

Explanation / Answer

A header file is a file with extension .h which contains function declarations and macro definitions to be shared between several source files.
There are two types of header files:
File that programmer writes
Default files which comes with compiler.

We need to include or import header files in source code where ever needs.
in case of java we will call it as packages

Including a header file is equal to copying the content of the header file but we do not do it because it will be error-prone and it is not a good idea to copy the content of a header file in the source files, especially if we have multiple source files in a program.

better way in C or C++ programs is that we keep all the constants, macros, system wide global variables, and function prototypes in the header files and include that header file wherever it is required.
