Three types of loops are used in bash programming. While loop is one of them. Like other loops, a while loop is used to do repetitive tasks. The starting and ending block of the while loop is defined by do and done keywords in the bash script. The termin
While Loops in Python A while statement in python sets aside a block of code that is to be executed repeatedly until a condition is falsified. The structure of a while loop allows the total number of iterations, or repetitions, to be unknown from the start. Examples of use cases might be...
Even though thefor loopachieves the same thing with fewer lines of code, you might want to know how a “while” loop works. Of course, if you know any other programming languages, it will be very easy to understand the concept of loops inPython. In this article, I shall highlight a ...
Here, we are going to learn about while and do...while loops. C++ while Loop The syntax of the while loop is: while (condition) { // body of the loop } Here, A while loop evaluates the condition If the condition evaluates to true, the code inside the while loop is executed. The...
There are 3 types of loops in C: while loop in C do – while loop in C for loop in C 1. while Loop in C While loop executes the code until the condition is false. Syntax: while(condition){ //code } Example: #include<stdio...
Integer[]array=newInteger[]{1,2,3,4,5};intindex=0;while(index<array.length)//Infinite Loop because we are not incrementing the index{System.out.println(array[index]);} The infinite loops, sometimes, result intoStackOverflowErrororOutOfMemoryErrorbased on what we are trying to do in the ...
While loop is mainly used when we do not know how many times a statement will be executed. In such a case, the number of iterations is unknown, and it depends on the condition inside the while loop.In C++, we can make use of nested while loops as well. Also, there are infinite loo...
WHILE loops are still slow and have a performance impact. If it is a nested loop, it will be even worse. In general, we should try to use set operations for the best performance. It is not easy, but it is usually the best way. Cursors and WHILE loops must be used carefully and on...
Sometimes we want a part of the code to keep running, again and again, until we are ready for it to stop. Let’s see how while loops can help us do this! Python While 1 Run the example: In this code, we import time so we can use a “wait” function called ...
Note that we could apply the same logic within other types of loops such as repeat-loops or while-loops.Video, Further Resources & SummaryWould you like to know more about loops? Then you may watch the following video of my YouTube channel. I’m explaining the R programming code of this...
