Provide Example of Function?

An illustration of a function definition

main()
{
message();
} /* header */

message()
{
/*bodystarts here*/
printf ("Example for function definition\n");
return;
}

The program will print the following output illustration for function definition

message() is the function here In all c programs, program execution begins in main() and when program control encounters message(), the function is invoked and program control is passed to it. After printing the message(), the program control passes back to the calling environment, which in above illustration is main() and when main() runs out of function calls the program ends.
