Causes the enclosing for, range-for, while or do-while loop or switch statement to terminate. Used when it is otherwise awkward to terminate the loop using the condition expression and conditional statements. Syntax attr(optional) break ; Explanation After this statement the control is transferred to the statement immediately following the enclosing loop or switch. As with any block exit, all automatic storage objects declared in enclosing compound statement or in the condition o

Usage break statement: as the declaration of the statement

Functions Defined in header <ctime> Time manipulation difftime computes the difference between times (function) time returns the current time of the system as time since epoch (function) clock returns raw processor clock time since the program is started (function) Format conversions asctime converts a tm object to a textual representation (function) ctime converts a time_t object to a textual representation (function) strftime converts a tm

Usage alternative operators: as an alternative for |

Syntax true (1) false (2) Explanation The Boolean literals are the keywords true and false. They are prvalues of type bool. Notes See Integral conversions for implicit conversions from bool to other types and boolean conversions for the implicit conversions from other types to bool. Example #include <iostream> int main() { std::cout << std::boolalpha << true << '\n' << false << '\n' <<

Usage bool type: as the declaration of the type
