Nov 25, 2013 · The idiom designed into the C language (and inherited into C++) for infinite looping is for(;;): the omission of a test form. The do/while and while loops do not have this special feature; their test expressions are mandatory. for(;;) does not express "loop while some condition is true that happens to always be true".
I've recently been through the same problem, and I found a solution that might help a lot of people. The function "scanf" leaves a buffer in memory ... and that's why the infinite loop is caused. So you actually have to "store" this buffer to another variable IF your initial scanf contains the "null" value.
Feb 13, 2012 · 28. If you are looking for "switching between 2 infinite loops" it could be "wrapped" by third loop and this "switching" could be done by simple break. But since you want your program to stop some day, this loop could be placed within the function and you could use return; for ending it: void myMagicLoop() {. for(;;) {. for(;;) {.
Apr 17, 2017 · Back in my C/C++ days, coding an "infinite loop" as. while (true) felt more natural and seemed more obvious to me as opposed to. for (;;) An encounter with PC-lint in the late 1980's and subsequent best practices discussions broke me of this habit. I have since coded the loops using the for control statement. Today, for the first time in a long ...
Mar 31, 2022 · You can use the break statement after determining that the input is valid. Until then, the loop will run forever. Instead of using a long chain of if... else if, in this case, you can simply use a switch statement, after making the letter upper-case using the function toupper. #include <stdio.h>. #include <stdlib.h>.
3. return immediately exits the function - regardless of the work program was doing. If you were executing the while(1) loop in the main function, return would immediately exit main function, which means it will quit the program and exit the infinite loop as well. If you were executing the loop in other function, say foo, return would still ...
Aug 30, 2013 · A better way to read input from the keyboard is to use fgets () where you specify a max length to read. Once you have the input you can use sscanf () to retrieve the numeric value from it. The ENTER till then not irritate your input. char buffer[128]; fgets( buffer, 128, stdin ); sscanf( buffer, "%d", &a );
May 17, 2011 · If you want to just pause your infinite loop in Turbo C then press the BREAK. If you want to get back to the editor of your program in Turbo C then press CTRL + BREAK. It will return back to editing your program. Yes, I tried this and it works! edited Dec 3, 2014 at 16:33.
Oct 26, 2010 · 9. Just do sleep(5) (include unistd.h). You can use it like this: If you're doing work inside the loop, you can do (include time.h): // do work here. Keep in mind that the while loop will take at least 5 seconds, it may take longer than 5 seconds if the work inside the loop takes a long time.
Apr 15, 2013 · There were too many comments; the 'infinite loop' comment was no longer accurate; the code in the loop was prompting and I'm blowed if I'm going to respond to prompts from a server process like that. Personal prejudices, that's all. –
