The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...
C while 循环 C 循环 只要给定的条件为真,C 语言中的 while 循环语句会重复执行一个目标语句。 语法 C 语言中 while 循环的语法: while(condition) { statement(s); } 在这里,statement(s) 可以是一个单独的语句,也可以是几个语句组成的代码块。condition 可

A loop is used for executing a block of statements repeatedly until a given condition returns false. In the previous tutorial we learnedfor loop. In this guide we will learn while loop in C. C– while loop Syntax of while loop: while(condition test){//Statements to be executed repeatedly/...
A while loop in C++ is an example of an entry-controlled loop wherein the condition is checked at the entry of the loop. The loop runs until the condition is true, and the statements/ block of code inside the body of the loop are executed. The loop terminates as soon as the ...
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:...

C语言中while和do–while循环的主要区别如下：1、循环结构的表达式不同 while循环结构的表达式为：while（表达式）{循环体}。do-while循环结构表达式为：do{循环体;}while (条件表达);。2、执行时判断方式不同 while循环执行时只有当满足条件时才会进入循环，进入循环后，执行完循环体内全部语句至当条件不...
