This article mainly introduces "Why the while sentence in C++ is better than the for sentence". In the daily operation, I believe that many people have doubts about why the while sentence is better than the for sentence in C++. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question "Why is the while sentence better than the for sentence in C++?" Next, please follow the editor to study!

ES.73: while statements are better than for statements if there are no obvious loop variables

Reason (reason)

Readability.

Readability

Example (sample)

Int events = 0

For (; wait_for_event (); + + events) {/ / bad, confusing

/ /...

}

The "event loop" is misleading because the events counter has nothing to do with the loop condition (wait_for_event ()). Better

Because the event count has nothing to do with the loop condition (wait_for_event ()), "event loop" is actually misleading. The better way to write it is:

Int events = 0

While (wait_for_event ()) {/ / better

+ + events

/ /...

}

Enforcement (implementation recommendations)

Flag actions in for-initializers and for-increments that do not relate to the for-condition.

Prompt if the loop variable initialization and the action in the incremental operation have nothing to do with the loop condition.

At this point, the study of "Why is the while sentence in C++ better than the for sentence" is over. I hope I can solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
