printing a square with diagonals

Question

I want to print this if the user typed in for example 2:

+---+ 
|\\ /|
| X |
|/ \\|
+---+

It\'s a square with a size of 2n+1 for each side of i

Here is a slightly modified version of your program that prints spaces where you don't specify anything else.

You can use it as a starting point.

#include 

int main(void)
{
    int size = 2;
    int i, j;
    char ch;

    for (int i = 0;i < ((size * 2) + 1);i++){
        for (int j = 0; j < ((size * 2) + 1);j++){
            ch = ' ';
            if (i == 0 && (j == 0 || j == size * 2)){
                ch = '+';
            }
            else if (i == 0 && j != i){
                ch = '-';
            }

            if (i > 0 && (j == 0 || j == size * 2)){
                ch = '|';
            }
            printf("%c", ch);
        }
        printf("\n");
    }

    return 0;
}

This prints

+---+
|   |
|   |
|   |
