Sentence: I doubted about the functionality of this code.

[Sureshvemuri]

Which one is the correct one to say:

"I doubted about the functionality of this code."
"I suspected about the functionality of this code."

(I mean - I thought the code would not run due to some reasons.)

Thanks,
Suresh

.
Neither. Use these:

"I doubted the functionality of this code."
"I suspected the functionality of this code."

It's better to say "I thought the code would not run due to some causes". See cause vs. reason for differences.

.
No, that's not so good, Anna.

Why Mr. M? I was taught that reason is usually for good/expected outcome while cause for something unexpected.
Could you shed some more light?

It is not a natural sentence. Native speakers front the negation to the main clause. 'Due to' is suspect here. 'Some causes' is unnatural; we would use the singular. 'Reason' is fine there anyway (you have some prescriptive difference which does not hold), though I would have the same complaints about Suresh's sentence--except that that sentence was not under consideration in this thread.
