function [A, varargout] = myfunc(x, y, z, optional) A = somefunction(x,y,z) if nargout == 2 && nargin == 4 i = find(A > optional); B = somefunction(A,i); varargout{1} = B; end In this way, you have an optional output associated to an optional input variable. It works...
Types of Input and Output FunctionsWe have the following categories of IO function in C −Unformatted character IO functions: getchar() and putchar() Unformatted string IO functions: gets() and puts() Formatted IO functions: scanf() and printf()...

So far we’ve encountered two ways of writing values:expression statementsand theprint()function. (A third way is using thewrite()method of file objects; the standard output file can be referenced assys.stdout. See the Library Reference for more information on this.) 我们有两种大相径庭的输出...

4、ted Output with printf,The printf() function prints output to stdout, according to format and other arguments passed to printf(). The syntax is: printf ( “format”, var1, var2, ) ; The string format consists of two types of items - characters that will be printed to the screen,...
type function(type input){ // modify input return input; } type output = function(input); Input and output in the same argument. Use with caution. Can return error. bool function(type& put){ return true; } It depends on your design. Don't need errors?... use a movable one. Need...
// Write to STDOUT and read from STDIN by using the default// modes. Input is echoed automatically, and ReadFile// does not return until a carriage return is typed./// The default input modes are line, processed, and echo.// The default output modes are processed and wrap at EOL.whil...
