The preceding example shows the elements of theforstatement: Theinitializersection that is executed only once, before entering the loop. Typically, you declare and initialize a local loop variable in that sectio
The declared variable can't be accessed from outside the for statement. The initializer section in the preceding example declares and initializes an integer counter variable: C# Copy int i = 0 The condition section that determines if the next iteration in the loop should be executed. If ...
Each iteration of the loop may be suspended while the next element is retrieved asynchronously. The following example shows how to use the await foreach statement:C# Cóipeáil await foreach (var item in GenerateSequenceAsync()) { Console.WriteLine(item); } ...

Example: Skipping Certain Iterations of for-LoopThe following syntax illustrates how to move to the next iteration in case a certain if-statement is TRUE. Let’s first create a basic for-loop in R:for(i in 1:10) { # Regular for-loop cat(paste("Iteration", i, "was finished.\n"))...
Much likeif/unlessmay be utilized post-statement, the same can be done withfor. Below are the same examples as above utilizing the postfix syntax: sum(nums)sum=0sum+=nforninnumsjoin(delim,args)buf=''buf+=i?delim+arg:argforarg, iinargs ...
To execute multiple statements, use a block statement ({ ... }) to group those statements. Example 1 The followingwhileloop iterates as long asnis less than3: let n = 0; let x = 0; while (n < 3) { n++; x += n; }
我们可以在 mixin 中使用循环实现更强大的功能,例如,我们可以把表达式对作为使用插值和循环的属性。 We can use iteration within mixins to produce powerful functionality. For example, we can apply expression pairs as properties using interpolation and iteration. ...
Give an example where iteration is useful in data processing? Let's say you have a large dataset and want to calculate the average of all the numbers. You can use iteration to iterate through each number in the dataset, sum them up, and then divide by the total count. By iterating thr...
