Well, yes? The function is declared to return char *, but you return i1 which is the input argument and has type int *. You might mean to return the newly allocated string dum, and perhaps also fill it with the data that was read using fgets() to the separate character array input. In this case, you need to copy the data over, … Read more
Notice you’re not dynamically allocating the variable, which pretty much means the data inside str, in your function, will be lost by the end of the function. You should have: Then, when you call the function, the type of the variable that will receive the data must match that of the function return. So, you should … Read more
You’re missing a return statement. When the compiler looks at your code, it’s sees a third path (the else you didn’t code for) that could occur but doesn’t return a value. Hence not all code paths return a value. For my suggested fix, I put a return after your loop ends. The other obvious spot – adding an else that had a return value to the if-else-if – … Read more
On the actual behavior, there is no difference. They all return None and that’s it. However, there is a time and place for all of these. The following instructions are basically how the different methods should be used (or at least how I was taught they should be used), but they are not absolute rules so you … Read more
In C# 7 and above, see this answer. In previous versions, you can use .NET 4.0+’s Tuple: For Example: Tuples with two values have Item1 and Item2 as properties.
Notice you’re not dynamically allocating the variable, which pretty much means the data inside str, in your function, will be lost by the end of the function.

You could simply use which does exactly the same as Your function will also return None if execution reaches the end of the function body without hitting a return statement. Returning nothing is the same as returning None in Python.
Either allocate the string on the stack on the caller side and pass it to your function: Or make the string static in getStr: Or allocate the string on the heap:
If you put a return statement in the if, while or for statement then it may or may not return a value. If it will not go inside these statements then also that method should return some value (that could be null). To ensure that, compiler will force you to write this return statement which is after if, while or for. But if you … Read more
