printf
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Floating point variable = %f The last variable only has four decimal places, but it was printed out to six. This can be altered by including other information along with the conversion specifiers, as follows. Floating point number to 4 decimal places: %.4f This is how you print a fixed width field: %7d %7d %7.4f %7.4f %7d %7d You can also change the justification so that the figures are left justified. %-7d %-7d %-7.4f Characters can also be printed: %c Please press RETURN to continue. That last printf cleared the screen by using the code \f. If you want to print the \ character, use \\ as the control code. Please enter a new integer for var1: %dNow, please enter another integer for var2: %dFinally, please enter a floating point number for fvar: %ftestfilewFile open failed. Please change directory to one which has write access. This is some text, and this is variable 1: %d Variable 2: %d Floating point variable: %.4f File close failed. Sorry! A text file called 'testfile' has just been created in the current directory.
