To create an infinite loop, you need to use one of the loop constructs (while, do while, or for) with a non-zero value as a test condition. Generally, 1 is used as the test condition, you can use any non-zero value. A non-zero value is considered as true.Example...
死循环(Infinite loops)。 嵌入式系统中经常要用到无限循环,你怎么样用C编写死循环呢? 这个问题用几个解决方案。我首选的方案是: while(1) { } ; 一些程序员更喜欢如下方案: for(;;) ;{ } ; 这个实现方式让我为难,因为这个语法没有确切表达到底怎么回事。如果一个应试者给出这个作为方案,我将用这个作为...
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<<1; goto A; return 0; } 5.使用递归函数 递归函数没有终止条件就容易造成死循环。 int fun(int...
How do you code an infinite loop in C?相关知识点: 试题来源: 解析 for(;;) { /* ... */ } 或 while(1) { /* ... */ } 1. `for(;;)`:C语言中for循环的三个表达式均可省略。当条件表达式空缺时,默认视为"真",因此循环体将无限执行。2. `while(1)`:在C语言中非零值为真。当使用...
Learn: How we can use a for loop as an infinite to hold (hang) the program or execute set of statements infinitely? Most of the places while (1) is used as an infinite loop. A for loop can also be used as an infinite loop.
infinite loop explicitly creates to achieve some requirement in an application. The loop structures we can use to create intentionally or explicitly infinite loop and run the code specified in a loop to repeatedly or infinite times. So we can use the following loops do create an infinite loop ...

When the conditional expression is absent, it is assumed to be true. You may have an initialization and increment expression, but C programmers more commonly use thefor(;;)construct to signify an infinite loop. Note− You can terminate an infinite loop by pressing the "Ctrl + C" keys. ...
