Infinite loop

[JonM]

What is the preferred implementation of an infinite loop?

Code:

for ( ; ; ) ...

or

Code:

while (1 == 1) ...

or

something else?

Thanks in advance.

In the TC, we allow the for loop example with all three expressions being empty for a deliberate infinite loop.

Code:

/* deliberate infinite loop */
for ( ; ; )
{
   ...
}

Yes I saw that it was allowed. Is while (1==1) also allowed? Which is preferred?

Hi Jon,

Looks like \"they\" said

Code:

/* deliberate infinite loop */
for ( ; ; )
{
   ...
}

was the allowed form is infinite loops. Given one way to write them, there is no need for alternatives.

I was taught Pascal back in the early 80's, and would like to write this in the following form. C99 defines a \"boolean\" type, so MISRA-C3 could be different!

Code:

/* deliberate infinite loop */
while(true)
{
   ...
}
