I applied online on their website.

A recruiter sent me an email with a login for a C/C++ quiz. The quiz asked some questions about memory allocation and potential bugs in code. All of them were multiple choice and pretty easy.

Some questions, though, I wasn't sure how to answer. For example:

(This isn't an actual question, just an example)

Is it possible for the following function to go into an infinite loop given an array and its size in C:

c void foo(int* array, int array_size) { int index = 0; for (; index < array_size; index++) array[index] = 0; }

Well, for some, I'm not sure. The problem doesn't clarify whether or not the user can provide a negative array size for the variable array_size. Using the word "possible," I put "yes" for most of the questions that asked that, but I'm not sure that's what they wanted, since it wasn't clarified.

Apparently, I didn't score high enough on the quiz, even though I had thought I got them all right.

Is it possible for the following function to go into an infinite loop, given an array and its size in C?

c void foo( int* array, int array_size ) { int index = 0; for( ; index < array_size; index++) array[ index ] = 0; }

Can this function enter an infinite loop?
