What is the difference of the structure "while" and repeat in Visualg? It can be exemplified?

loop while visualg portugol do-while

  • One will be executed while the condition is true. The other, will be repeated until the condition becomes true.

  • Simple answer, but it removed the doubts that I had. Obgd

The main thing is that the condition of enquanto is evaluated right on your entry, so can not even perform anything of the loop if the condition is already false, while (sorry the pun :) ), that the condition of the repita is only evaluated for the first time at the end of the first implementation of the block.

It’s different too because enquanto contained while (without pun) the condition is true, and in repita he repeats until he reaches that condition, so he repeats as long as the condition is false.

var i: inteiro
inicio
i <- 0
enquanto i < 10 faca
   escreva(i)
   i <- i + 1
fimenquanto

var i: inteiro
inicio
i <- 0
repita
   escreva(i)
   i <- i + 1
ate i >= 10

I put in the Github for future reference.

Behold What is the usefulness and importance of "do... while"?. The do-while is a mixture of the two. It always lets run once, but the output condition is the false, equal is in the while. In practice few languages, none strongly mainstream uses a construction equivalent to repita.

  • You can do the same "repeat" functions with the structure "while"?

  • You can always do the same thing, but it’s not always the most convenient way, so there are two ways.
