My previous article explains single looping statement in C#. This article explains nested looping statements. Nested looping is very important for manipulation sets of statements or data in any programming language. Definition One looping is insight; another looping is called nested looping. We could...

The infinite loop We can create an infinite loop using while statement. If the condition of while loop is alwaysTrue, we get an infinite loop. Example #1: Infinite loop using while # An example of infinite loop# press Ctrl + c to exit from the loopwhileTrue: num = int(input("Enter a...
such as with a wildcard, regular expression, or even an arbitrary script block. Since scanning through the text in a file is such a common task, PowerShell’sswitchstatement supports that directly. These additions make PowerShellswitchstatements a great deal more powerful than those in C and ...
It appears that there may be a typo in the statement "char *file_name" as the variable "file_name" is being used without first being assigned to any string. C read file line by line, If your task is not to invent the line-by-line reading function, but just to read the file line...
Swift programming language also provides a for-in loop that makes it easy to iterate over arrays, dictionaries, ranges, strings, and other sequences, i.e., we can use the for-in loop to iterate over a sequence. Practice theseSwift looping programsto learn the concept of looping (control ...
There are three main types of looping constructs in most programming languages: for loops, while loops, and do-while loops. For loops are used when the number of iterations is known in advance. The syntax of a for loop typically includes an initialization statement, a condition statement, and...
The $count++ syntax is equivalent to $count=$count+1, but the former is more common in Perl and C language programming. You can also decrement a value using the $count-- syntax. The foreach Statement The foreach statement provides yet another way to implement a loop in a Perl script....
Notice the statement, System.out.println(Arrays.toString(destination)); Here, the toString() method is used to convert an array into a string. To learn more, visit the toString() method (official Java documentation). 3. Copying Arrays Using arraycopy() method In Java, the System class cont...
