In this section, we are going to learn how to return an array in Java. Remember:
Example 1In the following example, the method returns an array of integer type. Output: Example 2In the following example, the method returns an array of double type. Output: Example 3In the following example, method returns an array of object type. Output: Next TopicJava Tutorial ← prev next → IntroductionIn this tutorial, we are going to understand how we can return an array from a function in C++. Methods to Return an Array in a C++ FunctionTypically, returning a whole array to a function call is not possible. We could only do it using pointers. Moreover, declaring a function with a return type of a pointer and returning the address of a C type array in C++ doesn’t work for all cases. The compiler raises a warning for returning a local variable and even shows some abnormal behavior in the output. Hence, returning an array from a function in C++ is not that easy. But we can accomplish that by following any of the below mentioned methods. Let’s get right into it. 1. Using PointersAs we mentioned earlier, returning a normal array from a function using pointers sometimes gives us unexpected results. But this behaviour and warnings can be avoided by declaring the array to be a Let us see how.
Output:
Here, we have declared the function As we can see from the above output, the array is successfully returned by the function. 2. Using a Structure in C++We can also make a function return an array by declaring it inside a structure in C++. Let us see how.
Output:
Here,
note that we have declared the array In this way using another structure variable 3. Using std::arrayFor
Output:
Hence it is clear from the output, that the array return by the function ConclusionSo in this tutorial, we learned about the different methods by which we can return an array from a C++ function. For any further questions, feel free to use the comments below. References
