statement - any statement, typically a compound statement, which is the body of the loop 解释 语句总是至少执行一次,即使表达式总是产生false。如果在这种情况下不应该执行,当或为可以使用循环。 如果需要在某个点终止循环的执行,断续语句可用作终止语句。

For example, let's say we want to show a message 100 times. Then instead of writing the print statement 100 times, we can use a loop. That was just a simple example; we can achieve much more efficiency and sophistication in our programs by making effective use of loops. ...
mysql存储过程之WHILE循环,LOOP循环以及REPEAT循环 在MySQL存储过程的语句中有三个标准的循环方式:WHILE循环,LOOP循环以及REPEAT循环。还有一种非标准的循环方式:GOTO,不过这种循环方式最好别用,很容易引起程序的混乱,在这里就不错具体介绍了。 这几个循环语句的格式如下:...

while是循环流程控制，使用的标准格式为 while(表达式){ 循环语句体；} 说明：①while循环的表达式是循环进行的条件，用作循环条件的表达式中一般至少包括一个能够改变表达式的变量，这个变量称为循环变量 ②当表达式的值为真（非零）时，执行循环体；为假（0）时，则循环结束 ③当循环体不需要实现任何...
Thewhilestatement can also terminate when abreak,goto, orreturnwithin the statement body is executed. Use thecontinuestatement to terminate an iteration without exiting thewhileloop. Thecontinuestatement passes control to the next iteration of thewhilestatement. ...
While loop is mainly used when we do not know how many times a statement will be executed. In such a case, the number of iterations is unknown, and it depends on the condition inside the while loop.In C++, we can make use of nested while loops as well. Also, there are infinite loo...
