Is there a label/goto in Python?
(22 answers)
Closed 7 years ago.
We can use goto and :label in batch.
Is there anything like it in Python?
No, there is no goto or label or other equivalent in vanilla python.
Your best bet is to stick with regular control flow statements (e.g. if, else if, else, for, while, break, continue, ...) and functions (which add return to the list of control flow statements as well ...)

If I have the following:
...
let p1 = <p>qwer</p>
let p2 = <p>asdf</p>
...
Should I put semicolons at the end of each of these?
It is not wrong to leave it like that, you can put semicolons if you want, but it is better you be consistent and follow one code style check https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode

What is the full "for" loop syntax in C?
(6 answers)
Closed 5 years ago.
My question is simple,thus I will not go in deep
can we use for() loop without condition like this
for(;;space+=1)
{
printf(" ");
break;
}
Of course you can. An empty condition is taken to evaluate to 1.
for (;;){/*ToDo - your code here*/} is idiomatic C.
Yes it is perfectly correct to do so.
But since you have provided a break immediately after printf, it will only execute once. I'm not sure whether this is what you wanted. But if so, then this works fine.

Is there an interpreter for C? [closed]
(13 answers)
Closed 7 years ago.
I'm not looking for csh, I'm looking for a shell for C similar to the Python or the Scala shells.
I understand that C is a compiled language, but is there anything out there that would let me quickly play around with things so I can e.g. better learn how pointers work? It should at least be theoretically possible to do this, wondering if anyone has taken the time to implement it.
As you well know that C is a compiled language. It is better to write C code than compile it, do some breakpoints, learn what value is in memory, where the pointer points etc.
But I think you mean this. Is there an interpreter for C?

I can write a FORTRAN function to find an available file unit, but I was certain there was already an intrinsic. But if there is, I can't find anything about it. Is there such a thing or am I dreaming?
UPDATE: Apologies for the duplicate. Did a search, but it didn't show up.
I guess, you are looking for newunit (available with F2008, shown at the bottom of that link in the Fortran Wiki).
Ups, has already been answered.
maybe you were thinking of inquire?

I'm building a compiler for a custom language. Is it possible for the compiler to detect any infinite looping condition without running the program?
If so how can I implement it?
You may be able to detect some infinite loops, but in general you can't detect all possible infinite loops (unless your custom language is specifically designed to eliminate general looping constructs). See http://en.wikipedia.org/wiki/Halting_problem.
