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....

Learn about the do...while loop in C++, its syntax, and how to use it effectively in your programs.

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 ...
Matlab has no do-while loop like c programming, cpp programming, and other programming languages. But instead of using do while loop works powerfully in Matlab. In Matlab, mainly two loops are used to do operations. If we are sure how many times we need to perform a particular task, the...
Moving forward, I think the 70s and 80s saw the rise of structured programming. Languages like C, C++, and Pascal come to mind. Structured programming introduced concepts like functions, loops, and recursion, which made programs easier to manage and less error-prone. C was developedin1972, ri...
Introduction to loops And now the real fun begins -- in the next set of lessons, we’ll cover loops. Loops are control flow constructs that allow a piece of code to execute repeatedly until some condition is met. Loops add a significant amount of flexibility into your programming toolkit, ...
While in most circumstances using eof() to control input loops is a bad idea it is possible to use eof() if done properly. What you will need to do is pre-read the information before the loop, the at the end of the loop read another time: 1234567891011121314151617 ifstream fin("datafi...
