Praxisbeispiel 1 f\u00fcr die do-while-Schleife:<\/strong><\/p>\n\n\n\n#include <iostream>\nint main() {\n\nunsigned i = 1;\nunsigned benutzer = 0;\nstd::cin >> benutzer;\n\ndo\n{\nstd::cout << i << std::endl;\n++i;\n}\n\nwhile (i <= benutzer);\n\n}<\/code><\/pre>\n\n\n\n
Auch diesen Code k\u00f6nnte man etwas optimieren und dem Benutzer auch Anweisungen in das Terminal schreiben, damit er wei\u00df was hier gemacht werden soll. Der angepasste Code k\u00f6nnte so aussehen\u2026:<\/p>\n\n\n\n#include <iostream>\nint main() {\n\nunsigned i = 1;\nunsigned benutzer = 0;\nstd::cout <<\"Bitte geben Sie eine Zahl ein und dr\u00fccken dann Enter\"<< std::endl;\nstd::cin >> benutzer;\n\ndo\n{\nstd::cout << i << std::endl;\n++i;\n}\nwhile (i <= benutzer);\n}<\/code><\/pre>\n\n\n\n
