putting a number in a hollow shape - c

Question

I want to put number that can be one,two,three,four and so forth digits in the shape. Nonetheless, extra spaces is shifted. Besides, center is shifted. I trying different ways,however,i can't. How can i fix the problem. Thank you for all appreciated answer.
output example is:

#include <stdio.h>
/* Function Prototypes */
int countNumber(int number);
int main() {
int n; /* number to put in the center of the shape */
int column, row; /* take values of column and row via user */
int columnCount, rowCount; /* count number of column and row */
int i; /* count how many spaces remained */
printf("Enter column:\n>");
scanf("%d",&column);
printf("\nEnter row:\n>");
scanf("%d",&row);
printf("\nEnter number for center:\n>");
scanf("%d",&n);
if((10<column && column<40) && (10<row && row<40)){
for (columnCount = 0; columnCount < column; columnCount++) {
for (rowCount = 0; rowCount < row; rowCount++) {
/* Middle Row */
if (columnCount == column/2) {
printf("#");
for (i = 0; i < ((row*2-3)-countNumber(n))/2;i++)
printf(" ");
printf("%d", n);
for (i = 0; i < ((row*2-3)-countNumber(n))/2;i++)
printf(" ");
printf("#");
break;
}
if (columnCount==0 || columnCount==column-1 || rowCount==0 || rowCount==row-1)
printf("# ");
else
printf(" ");
}
printf("\n");
}
}
else
printf("Please enter value btw 10-40");
return 0;
}
/* Function */
int countNumber(int number) {
int count;
for(count=0;0<number;count++) /* the number how many decimal places have */
number/=10;
return count;
}

Answer 1

this one works with any number
#include <stdio.h>
int digits(int n)
{
int i;
for(i=0;n;i++,n=n/10);
return i;
}
int main()
{
int i,j;
int column,row;
int n,cnt;
printf("Enter column: ");
scanf("%d",&column);
printf("Enter row: ");
scanf("%d",&row);
scanf("%d",&n);
cnt=digits(n);
for(i=0;i<row;i++)
{
for(j=0;j<column;j++)
{
if(i==0 || i==(row-1) || j==0 || j==(column-1))
printf("*");
else if((i==(row/2)) && (j==((column-cnt)/2)))
{
printf("%d",n);
j=j+(cnt-1);
}
else
printf(" ");
}
printf("\n");
}
return 0;
}

Answer 2

This should work!
It still has a small margin of error but I try to solve it
/*Import*/
#include <stdio.h>
/*Function Prototyp*/
int countNumber(int number);
int main() {
/*Variable*/
int number, column, row;
int columnCount, rowCount;
int i;
printf("Enter column:\n>");
scanf("%d",&column);
printf("\nEnter row:\n>");
scanf("%d",&row);
printf("\nEnter number for center:\n>");
scanf("%d",&number);
for (columnCount = 0; columnCount < column; columnCount++) {
for (rowCount = 0; rowCount < row; rowCount++) {
//Middle Row
if (columnCount == column/2) {
printf("*");
for (i = 0; i < ((row*2-3)-countNumber(number))/2;i++)
printf(" ");
printf("%d", number);
for (i = 0; i < ((row*2-3)-countNumber(number))/2;i++)
printf(" ");
if (countNumber(number % 2 == 0))
printf(" *");
else
printf("*");
break;
}
if (columnCount==0 || columnCount==column-1 || rowCount==0 || rowCount==row-1)
printf("* ");
else
printf(" ");
}
printf("\n");
}
return 0;
}
int countNumber(int number) {
int count;
for (count = 0; number > 0; count++)
number = number / 10;
return count;
}
