I want the body back from the function, but I'm making a mistake. C++

[jules]

I wanted to do a function that would create a mass and return it to the main, but something went wrong. Explain where I did wrong.

#include <iostream>
using namespace std;
int create_board () {

int board[10];

for (int i = 0;i<10;i++) {

board[i] = i;

}

return board;

}
int main () {

int board = create_board();

for (int i = 0;i<10;i++) {

cout >> board[i] << " ";

}

}

First,in functions create_board variable board You have a type. const int * (i.e. mass int) And you're trying to make this variable-type meaning. int here:

int board = create_board();

I think it makes a mistake to make a difference. Should be replaced by:

int* board = create_board(); // Звёздочка после int 

and the designation of the function, respectively,

int* create_board ()

SecondWhen you do this:

int board[10];

memory underground is emitted in the glass ( https://ravesli.com/urok-105-stek-i-kucha/ ) And all memory in the glass shall be cleaned when the relevant variable comes out. https://ravesli.com/urok-48-lokalnye-peremennye-oblast-vidimosti-i-vremya-zhizni/ ♪ In summary, as soon as your code reaches the figure boxes that complete the function create_boardthe memory of the mass board it is cleared and, therefore, all values in it become inaccessible. There's a mistake.

Now what to do with it. If it's so bad with the glass, you're gonna have to remembrance it in a pile of dynamism, replacing it with:

int board[10];

Here's this:

int* board = new int[10];

Attention, don't forget to clear your memory when you don't need it, so:

int* board = create_board(); // Создаёте массив
//... Используйте массив, как хотите
delete[] board; // Когда стал не нужен, чистите память

ThirdWell, at the end of the day, where does the sign of the space in the flow be placed? cout? This one. <<! You have one, then another. ♪ ♪

P.S. In the notebook, you write your code... IDE, the majority of these mistakes should have told you.
