Draw a pattern using for loops in C - c

Question

Can you guys please help me out here?
I have to print that kind of pattern Example for pattern
in that example the input for the size is 21.
for (int row = 0; row < size; row++)
for (int col = 0; col < size; col++) {
if (row == 0 && col == 0 || row == 0 && col == size - 1 || row == size - 1 && col == 0 || row == size - 1 && col == size - 1)
printf("+");
if ((row == 0 || row == size - 1) && (col > 0 && col < size - 1))
printf("-");
if ((row > 0 && row < size - 1) && (col == 0 || col == size - 1))
printf("|");
if ((row > 0 && row < size - 1) && (col > 0 && col < size - 1)) {
if (row == col)
printf("\\");
else
if (col == size - 2)
printf("/");
else
if (row == x && col == x)
printf("X");
else
printf(" ");
}
}
This is the code i wrote but it is not good .
How can I fix it ?
Thank you!

Here is another solution ,
int main()
{
int size =5;
int counter = 0;
printf("+");
for(int k=1;k<=size+1;k++){
printf("-");
}
printf("+");
printf("\n");
}
for(int i=1;i<=size;i++){
printf("|");
for(int j=1;j<=size;j++){
if(j==0 || j==i )
printf("\\");
else
printf(" ");
if(counter==0){
if(j==size){
printf("/");
counter++;
}
}
else if(j==size-i+1)
printf("/");
if(j==size)
printf("|");
}
printf("\n");
}
printf("+");
for(int k=1;k<=size+1;k++){
printf("-");
}
printf("+");
printf("\n");
return 0;
}

You missed couple of things, read the comments in the code below to check what I corrected.
Here is the working code:
#include <stdio.h>
int main(void)
{
int size = 21;
int x = size / 2; // You want x in the middle so its size / 2;
int i = 1;
for (int row = 0; row < size; row++, i++) // Incrementing 'i' too
{
for (int col = 0; col < size; col++)
{
// In this first if statement below you should put parenthesis around && conditions for better readability and to get rid of any warnings compiler might put out
if ((row == 0 && col == 0) || (row == 0 && col == size - 1) || (row == size - 1 && col == 0) || (row == size - 1 && col == size - 1))
printf("+");
if ((row == 0 || row == size - 1) && (col > 0 && col < size - 1))
printf("-");
if ((row > 0 && row < size - 1) && (col == 0 || col == size - 1))
printf("|");
if ((row > 0 && row < size - 1) && (col > 0 && col < size - 1))
{
if (row == x && col == x) // This should be your first check because in case you are in the middle you want to put 'x' and don't care about rest of the if-else statement
printf("X");
else if (row == col)
printf("\\");
else if (col == size - i) // Instead size - 2, you put here size - i, which is initialized to 1 and incremented by 1 in the outer for loop
printf("/");
else
printf(" ");
}
}
printf("\n"); // You want to print out the new line at the end of every row
}
return 0;
}
