1. Syntax The for-each loop does not use the index variable. It uses a variable of the base type of the Collection or the array we will iterate, followed by a colon and finally the array/collection itself. In th
Thefor-loopstatement in Java provides a compact way to iterate over the arrays or collection types using a counter variable that is incremented or decremented after each iteration. Programmers often refer to it as thetraditional “for loop”because of the way it repeatedly loops until a particular...

Now that we have a clear understanding of the syntax and functionality of the for loop in C++, let's look at a few code examples. Example 1: To Find The Factorial Of A Number Using For Loop In C++ In this example, we’ll use a C++ for loop to calculate the factorial of a given...
In the above example, the work is the println() that prints something out for each iteration. increment -- code in the body that advances things so we are closer to making the test false. At the end of the body, the code will loop around to the top of the body. Sometimes, some ...
可以通过ls -l /bin/*sh命令看到: 所以在使用sh命令执行脚本的时候实际使用的是 dash,而 dash 不支持这种 C 语言格式的 for 循环写法。 解决方法:使用bash代替sh运行脚本: bash test.sh
