do{}while(1)语句使用的不多,因为也会需要在执行语句之后判断条件,会浪费单片机的资源。 4.goto语句 loop: //code goto loop; 实际的嵌入式开发中,很少使用goto语句,但是也可以使用goto语句编写死循环。 #include<iostream> using namespace std; int main() { //用goto实现infinite loops(死循环) A: cout...
Flowchart of while loop Working of while loop Example 1: while loop // Print numbers from 1 to 5 #include <stdio.h> int main() { int i = 1; while (i <= 5) { printf("%d\n", i); ++i; } return 0; } Run Code Output 1 2 3 4 5 Here, we have initialized i to 1...
C do...while 循环 不像for 和 while 循环,它们是在循环头部测试循环条件。在 C 语言中,do...while 循环是在循环的尾部检查它的条件。 do...while 循环与 while 循环类似,但是 do...while 循环会确保至少执行一次循环。 语法 do{ statement(s); }while( condition ); 请注意,条件表达式出现在循环的尾部...
第一种方式就是 条件控制的循环(Condition Controlled Loop),由一个给定的条件来控制,第二种方式就是 计数控制的循环(Counter Controlled Loop),重复处理的次数是已知的, 循环结构的两种实现方法如下图 “当”型循环如上图所示,它是先测试循环条件P,根据测试条件如果为真则执行循环体,否则退出循环, “直到”型循...
while loop Flowchart Syntax while(test condition){ //code to be executed } If the test condition inside the () becomes true, the body of the loop executes else loop terminates without execution. The process repeats until the test condition becomes false. Example: while loop in C // ...
while循环是一种先判断条件，再执行循环体的循环结构。当条件为真时，循环体会反复执行；当条件为假时，...
C for Loop In programming, a loop is used to repeat a block of code until the specified condition is met. C programming has three types of loops: for loop while loop do...while loop We will learn aboutforloop in this tutorial. In the next tutorial, we will learn aboutwhileanddo......

STATEMENT -> WHILE LP TEST RP STATEMENT STATEMENT -> DO STATEMENT WHILE LP TEST RP SEMI 1. 2. 其中,WHILE , DO 对应的就是while 和 do 两个关键字, TEST对应while后面的循环条件。根据语法表达式,我们可以构造对应的语法执行树,在codeTreeBuilder.java中,添加如下代码: ...
