I'm writing a code in C to read matrixes (square matrix with 3 <= dim <= 9) from a .txt file and print it exactly how it is written. The file is arranged as follows:

5
AAAAA
AAAAA
AAAAA
AAAAA
AAAAA
6
XXXXXX
XXXXXX
XXXXXX
XXXXXX
XXXXXX
XXXXXX

The first number indicates the size of the subsequent matrix.

I wrote the following code:

int main () 
 FILE *arquivo;
 char A[9][9];
 int N;
 int i,j;
 char temp;
 arquivo = fopen("matrizes.txt", "r");
 if (!arquivo) printf("Erro.n");
 while (fscanf(arquivo, "%d", &N) != EOF) 
 printf("%d n", N);
 fgetc(arquivo);
 for (i = 0; ((i < N) && (temp = fgetc(arquivo)) != 'n') ; i++) 
 for (j = 0; j < N; j++) 
 A[i][j] = temp;
 
 
 for (i = 0; i < N; i++) 
 for(j = 0; j<N; j++) 
 printf("%c", A[i][j]);
 
 puts(" ");
 
 
 return 0;

The output is this

5 
AAAAA 
AAAAA 
AAAAA 
AAAAA 
AAAAA 
5 
AAAAA 
AAAAA 
AAAAA 
AAAAA 
AAAAA

XXXXXX 
XXXXXX

6 
XXXXXX 
XXXXXX 
XXXXXX 
XXXXXX 
XXXXXX 
XXXXXX 

I honestly have no idea why this is happening. I tried different conditions to stop the loop, bot none of them worked out.

If I change

while (fscanf(arquivo, "%d", &N) != EOF)

into

while (fscanf(arquivo, "%d", &N) == 1)

the output is just

5
AAAAA
AAAAA
AAAAA
AAAAA
AAAAA

The value of the second loop scanf in this case is "0".
How can I fix it and print exactly what is written on the file?

By the way, I know there are other forms to print a .txt exactly how it is made, I mean, I don't need 2D arrays to do this. However, I will use this program to read several matrixes and do some tests with them (also I want to print them as well), so I really need to store the data in a matrix of characters.

The problem is here.

 for (i = 0; ((i < N) && (temp = fgetc(arquivo)) != 'n') ; i++) 
 for (j = 0; j < N; j++) 
 A[i][j] = temp;
 
 

The loop will exit once it sees a newline and start the while loop again.

Instead you want to read N lines.

 for (i = 0; i < N; i++) 
 for(j = 0; (temp = fgetc(arquivo)) != 'n'; j++ ) 
 A[i][j] = temp;
