In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software.. Most keyboard shortcuts require the user to press a single key or a sequence of keys one after the other.
For example, printf ("%*d", 3, 10) outputs 10 where the second parameter, 3, is the width (matches with *) and 10 is the value to serialize (matches with d). Though not part of the width field, a leading zero is interpreted as the zero-padding flag mentioned above, and a negative value is treated as the positive value in conjunction with the ...
Here are some Windows key commands and what they do: Windows key (Win): opens the Start menu on your computer. Windows button + Tab: switch your view from one open window to the next.
In Unix and Unix-like operating systems, printf is a shell builtin (and utility program [2]) that formats and outputs text like the same-named C function. Originally named for outputting to a printer, it actually outputs to standard output. [3] The command accepts a format string, which specifies how to format values, and a list of values.
Neither approach works to produce the DEL character because of its special location in the table and its value (code 127 10), Ctrl-? is sometimes used for this character. [ 5 ] When the control key is held down, letter keys produce the same control characters regardless of the state of the shift or caps lock keys.
On IBM PC compatible personal computers from the 1980s, the BIOS allowed the user to hold down the Alt key and type a decimal number on the keypad. It would place the corresponding code into the keyboard buffer so that it would look (almost) as if the code had been entered by a single keystroke.
The return value of the printf function is of type int, but it is silently discarded since it is not used. (A more careful program might test the return value to check that the printf function succeeded.) The semicolon ; terminates the statement. The closing curly brace indicates the end of the code for the main function.
