In this chapter we will examine the first three types of loops. The for each loop construct will be explained in Chapter 14 as this type of loop is only used to access the contents of an array. We shall begin by examining the while loop.PHP and MySQL Manualdoi:10.1007/978-0-85729-404-3_12PhD Simon Stobart BAMike Vassileiou
Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
PL/SQL Loops Explained - Explore the various types of PL/SQL loops, including FOR, WHILE, and LOOP statements, to efficiently manage repetitive tasks in your Oracle database applications.
When the macro runs it will set the variable equal to the first number in the For line. When the macro hits the Next line, it will add 1 to the value of the variable, or count up. So, i = 2 in the second iteration of the loop. It continues to loop until the last number in ...
Believe it or not, we actually used aninfinite loopin the last practical example above. So, how do we deal withinfinite loops? Python Break And Continue Statements As we explained above, there are cases where we will need to write intentionalinfinite loops. In these cases, we will see that...

Loops are an essential part of Visual Basic for Applications and (more generally) any programming language. From a general perspective,the main beauty of Excel VBA loops is the fact that, as explained above, they allow you to repeatedly execute certain statements. In other words: Loops allow ...
The Exit for statement functions almost the same as the “Exit Sub” or the “Exit Function” statements I had explained in two of my articles earlier. The only main difference is that it exits only one essential part of the huge code and proceeds with the execution of statements under the...

Example 1 explainedi:=0; - Initialize the loop counter (i), and set the start value to 0 i < 5; - Continue the loop as long as i is less than 5 i++ - Increase the loop counter value by 1 for each iterationExample 2 This example counts to 100 by tens: package main import ...
