Getting code that is easy to modify and read is very difficult, and writing the code in a professional way is the main factor for the success of any program, and the reason for this is to have a very popular format and organization for all programmers, which leads to the maintenance of the code permanently.
Do not forget that some iterative loops may reach approximately 500 lines. Yes, this is the truth when calling big data and applying some conditions to each other while running the code to increase the size of the code and reach large numbers of lines.
Therefore, Loops is a professional way to write code that enables everyone to understand a code and use it again in their programs with some modifications.
Shorten The Time
Well, if you do not have a strong knowledge of programming languages, you will face many difficulties in fetching this data, which may have to be printed one by one, which hinders your performance in executing the program quickly or moving to the next stage of development.
I have defined an iterative loop in this code consisting of a variable i, which calculates the number of rounds in the iteration, which was 20 cycles, and this means that I told the CPU to define a counter of type integer and its value is zero and if the value is still less than or equal to 20 then increase this variable and after each In addition, enter Body and execute the code inside, then return again until you finish all the cycles, which will stop when you reach the number 20.
When you apply this code in your browser, nothing will happen. Why?
Because we have reserved the For clause in memory to run without executing any internal code. If you want to see the result yourself, copy the code into your browser and print any value between brackets to see how Looping is work.
I do not think that you will find it difficult, as it is not very different from the previous For Loops and it works exactly as it should, but some programmers prefer this method instead of For or Do while.
Note with me that I defined a variable and gave it a zero value. Then I used a reserved statement do and parentheses and inserted the code inside with increasing the value of the variable in each cycle and put the condition at the end of the code.
