与while循环顶部测试循环条件的for和while循环不同,C编程中的do...while循环检查循环底部的条件。 do...while循环类似于while循环,除了它保证至少执行一次的事实。 语法(Syntax) C编程语言中do...while循环的语法是 - do { statement(s); } while( condition ); 请注意,条件表达式出现在循环的末尾,因此循环中...
The do-while statement lets you repeat a statement or compound statement until a specified expression becomes false. Syntax iteration-statement: do statement while ( expression ) ; The expression in a do-while statement is evaluated after the body of the loop is executed. Therefore, the body ...
The syntax for ado whilestatement is: doloop_body_statementwhile(cond_exp); where: loop_body_statementis any valid C statement or block. cond_expis an expression that is evaluated at the end of each pass through the loop. If the value of the expression is "false" (i.e., compares equ...

Rust也有一个专门的bool类型。它不能与整数隐式转换,否则就是一个u8,保证具有0x00或0x01的值,以及各自的字面意义false和true。bool支持所有的位操作,是唯一与短路的&&和||兼容的类型。它也是唯一可以在if和while条件下使用的类型。 整数有一套广泛的内置位操作,以方法的形式暴露出来,如x.count_zeros()和x.next...
