First, your code is not valid C. Returning an array by reference from a function. How to declare function returning array of Integer pointers.Returning values from a function. Returning arrays and Objects in C. C: Using and returning character arrays from functions, return type or reference? Im trying to create a null terminated string outside of a function, then run a function which will assign some data to it. For example, char abc  is created in m. cout << "The total of the array is: " getTotal(fives, ROWS) return 0Otherwise, a copy of the array that is passed to the function is constructed, In C and C, arrays are passed by pointer. C does not allow to return an entire array as an argument to a function .If you want to return a single-dimension array from a function, you would have to declare a function returning a pointer as in the following example I have a function that needs to return 3 int values. In the interests of completeness Ill suggest another method. Lets assume that you really need 3 values and not 300. In this article, youll learn to pass an array to a function in C.

If your arrays are fixed size, you can change the signature of the functions to require it (and incidentally build, which is good, right?): ?? add(T (a), T (b)) But you are left with what to return from there of course the answer is Matrix, right? Adding two matrices returns a matrix Basically, my question is how do you return a reference to an array that is defined in the function?What is the function in C returns the current directory?

C function return 2d array.The function only banks on what the caller passes in as the dimension(s).
Programming. C/C.In my program, I declare a 2-dimensional array, and I then want to create a function that returns it so I can access it elsewhere. Ive never been good at pointers, though, and Im having a hard time figuring out how to do this. So what I am trying to achieve is to return a pointer to a 2D array from the function so it could accessed in main(). I know there are some C libraries that does it for you like std::vector but I am trying to avoid dynamic memory allocation since I am working on embedded board (STM32) so I will Learn c - c tutorial - passing-2d-array-to-function-c - c examples - c programs.C Program to display the elements of two-dimensional array by passing it to a function.return 0
