Functions • Key points – fun(xx, yy, ii, jj) is a function call – xx, yy, ii, jj are called arguments – the parameters x, y, i, j are used as local variables within the function – the initial values of x, y, i, j correspond to the passed arguments xx, yy, ii, jj – the return expression; statement assigns the value of expression to the function and then returns to the calling function (main, in this case) Copyright © 2007 David Vernon (www.vernon.eu)
Functions • Key points – The type of each parameter must be specified: float fun(float x, float y, int i, int j) // correct float fun(float x, y, int i, j) // incorrect – We can omit the parameter names in the function declaration (but not the definition) but it’s not good practice float fun(float, float, int, int) // declaration in // main() – A function may be delared either inside a function that contains a call to it or before it at the global level Copyright © 2007 David Vernon (www.vernon.eu)
