The while loop in C++ first checks the test condition to see if the loop body will be executed. Learn about while, nested, and infinite while loops with examples.
The statements in the body are executed until the expression is evaluated to false. i++; This is the last, third phase of the while loop: the updating. We increment the counter. Note that improper handling of the while loops may lead to endless cycles. ...
The while loop loops through a block of code as long as a specified condition is true:Syntax while (condition) { // code block to be executed }In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5:...
The only exceptions are the loops where expression is a constant expression; while(true) is always an endless loop. As with all other selection and iteration statements, the while statement establishes block scope: any identifier introduced in the expression goes out of scope after the statement....

If, for, while and do/while loops do not need to define a block for just 1 line, but a good habit would be to use the {}s even for just 1 line in case you have to add more late. This way you will not have to remember to add them later. Once you get use to it you do ...
hi guys, i am new to programming and so far i am familiar with nested for loops. I don't understand how do while loops can be nested. What is the main difference between all the loops and how do you know which one to use ? or write? i took a second year computer engineering cour...

Edit & run on cpp.sh Nov 27, 2019 at 12:58am deleted account xyzzy(5768) Which "while" loop isn't repeating? You have 1 "do-while" loop, lines 8 - 53, and two "while" loops, lines 16-20 and lines 27-49. (Your indentation formatting needs a bit of work) ...
