C 程序打印完整的金字塔

Question

我有这个程序来解决完整的金字塔问题。

#include <stdio.h>

int main() {
  int i, j, rows;
  printf("Enter the number of rows: ");
  scanf("%d", & rows);
  for (i = 1; i <= rows; ++i) {
    for (j = 1; j <= i; ++j) {
      printf("%d ", j);
    }
    printf("\n");
  }
  return 0;
}

输出是这样的

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5

如何将其打印为完整的金字塔？再次从左侧打印相同的内容。

期望的输出:

   1   1
  12   12
 123   123
1234   1234

我认为您正在寻找这样的东西:

#include <stdio.h>

int main() {

    int rowCount, numberCount, rows;

    printf("Enter the number of rows: \n>");
    scanf(" %d", &rows);

    for(rowCount = 1; rowCount <= rows; rowCount++) {

        for(numberCount = rowCount; numberCount < rows; numberCount++)
            printf(" ");

        for(numberCount = rowCount; numberCount >= 1; numberCount--)
            printf("%d",numberCount);

        printf("   ");

        for(numberCount = 1; numberCount <= rowCount; numberCount++)
            printf("%d",numberCount);

        printf("\n");
    }


    return 0;

}
