    The comment says it all. Is there something you're having problems with?

    I think, "malloc in one function and free in other" is very bad thing. By the way, you needn't malloc at all. Just create a static array of constant strings and return appropriate string from array. What's problem?

    Sometimes it's the best option available though.

    You mean apart from the fact it's at odds with the requirements of the OP's particular homework exercise?

    In general, use of statics imposes limits on ability to use a function. Such as non-reentrancy (and eliminating recursion), unsafe in multithreaded code, and it is often unsafe to use the function twice within one expression.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.

    In this case it would be fine, were it not for the admonition to use malloc: the comment says "helper function for printRecord", so it is reasonable to suppose that the string will not be modified. Therefore, even with the use of a static local variable, the output of the function depends on the input, and not on any saved state that can vary from function call to function call.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
