constarr=["JavaScript","PHP","Python","Java"];for(letkeyinarr){console.log(key+": "+arr[key])}// Output:// "0: JavaScript"// "1: PHP"// "2: Python"// "3: Java" And in the loop, we’re rendering the index and the value of each array element. ...
The numeric part of these strings is the corresponding ID No. We will create a user defined function to find the numeric part from the string using a For Next loop to loop through each character in the string. Copy the following code into your module. Function NUMERIC_VALUE(value As Range...
While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a specific condition is true. What Is A For Loop In C++? A for loop in C++ language...
Java采用“for”(而不是意义更明确的“foreach”)来引导这种一般被叫做“for-each循环”的循环,并使用“:”(而不是意义更明确的“in”)来分割循环变量名称和要被遍历的对象。这样作的主要原因,是为了避免因为引入新的关键字,造成兼容性方面的问题――在Java语言中,不允许把关键字当作变量名来使用,虽然使用“for...

In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it. In this tutorial, we will e

Unlike Java and other programming languages, there is no traditional for loop in Kotlin.In Kotlin, the for loop is used to loop through arrays, ranges, and other things that contains a countable number of values.You will learn more about ranges in the next chapter - which will create a ...
Looping without a for loop 现在我们已经学习了 iterator 以及next和iter函数。我们将要尝试不通过 for 循环来遍历一个 iterable。 我们尝试将 for 循环转成 while 循环: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 deffunky_for_loop(iterable,action_to_do):foriteminiterable:action_to_do(item) ...
The loop is started with the keywordfor. We then specify that the data in our array are strings. Next, we choose a variable name to refer to the elements in the array as we iterate through the loop. In this case, we usedword. This is followed by a colon and the name of the array...
