把一个数字放在一个空心的形状上

Question

我想把数字，可以是一，二，三，四等数字的形状。尽管如此，额外的空间还是会被移动。另外，中心移动了。我试着用不同的方法，但是，我不能。我怎么能解决这个问题。谢谢大家的回答。

#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);

        }
        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;

这应该管用！

它仍然有很小的误差，但我试图解决它。

/*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;
}
