Loop is used in programming to repeat a specific block of code until certain condition is met (test expression isfalse). Loops are what makes computers interesting machines. Imagine you need to print a sentence 50 times on your screen. Well, you can do it by using print statement 50 times...
The PHP do-while loop is a control structure that executes a block of code at least once, then repeats while a condition remains true. Unlike regular while loops, do-while checks the condition after each iteration. Basic DefinitionsThe do keyword starts a do-while loop that always executes ...
whileanddoloops are used to repeatedly execute an expression until a test expression evaluates asfalse. Thewhileloop anddoloop are simple variants of one another. The syntax is: do<expr>while<expr>while<expr>do<expr> Both loops repeat thedo <expr>as long as thewhile <expr>evaluates to the...
*This program is written in Python, which I’ve used here because its syntax is easier to follow. The above program simply instructs the computer to keep on adding 2 to the initial value of i (i.e. 0) until it reaches the final value (i <= 1000). ...
