int main(void) The standard committee has also introduced that int main(int argc, char *agrv[]), which means that series of functions pass kind of additional information to the invoked program. However, main is still defined to take two parameters for these functions; the environment information is assigned to an external object extern char **environ.
You define a function using the rule we applied with the main() function. Define it starting with its return value (if none, use void), followed by the function name, its argument (if any) between parentheses, and the body of the function. Once you have defined a function, other functions can use it.f you declare a function that is returning anything (a function that is not void), the compiler will need to know what value the function returns. The return value must be the same type declared. The value is set with the return keyword.
