C 程序检查数字是否是克里希纳穆蒂数

编写一个 C 程序，使用 for 循环检查该数字是否是克里希纳穆蒂数。首先，如果数字等于其各位数字的因子之和，则它是一个克里希纳穆蒂数。此 C 示例将数字分解为各位数字，并找到每个数字的因子之和。接下来，如果条件检查总和是否等于实际数字且为真，则它是一个克里希纳穆蒂数。

#include <stdio.h>
int main()
{
  long fact;
  int Number, tempNum, rem, Sum = 0, i;
  
  printf("Enter Number to Check for Krishnamurthy Number = ");
  scanf("%d", &Number);

  for (tempNum = Number; tempNum > 0; tempNum = tempNum / 10)
  {
    fact = 1;

    rem = tempNum % 10;

    for (i = 1; i <= rem; i++)
    {
      fact = fact * i;
    }

    Sum = Sum + fact;
  }

  if (Number == Sum)
    printf("\n%d is a Krishnamurthy Number.\n", Number);
  else
    printf("\n%d is not a Krishnamurthy Number.\n", Number);
}

此 C 程序使用 while 循环检查给定数字是否为克里希纳穆蒂数。

#include <stdio.h>
int main()
{
  long fact;
  int Number, tempNum, rem, Sum = 0, i;

  printf("Enter Number to Check for Krishnamurthy Number = ");
  scanf("%d", &Number);

  tempNum = Number;
  while (tempNum > 0)
  {
    fact = 1;
    i = 1;
    rem = tempNum % 10;
    while (i <= rem)
    {
      fact = fact * i;
      i++;
    }
    Sum = Sum + fact;
    tempNum = tempNum / 10;
  }
  if (Number == Sum)
    printf("\n%d is a Krishnamurthy Number.\n", Number);
  else
    printf("\n%d is not a Krishnamurthy Number.\n", Number);
}

Enter Number to Check for Krishnamurthy Number = 40585

40585 is a Krishnamurthy Number.


Enter Number to Check for Krishnamurthy Number = 2248

2248 is not a Krishnamurthy Number.

在此 C 示例中，Calculate_fact 返回数字的阶乘，Krishnamurthy_Number 将数字分解为各位数字并找到阶乘之和。最后，此 C 程序打印 1 到 N 或给定范围内的克里希纳穆蒂数。

#include <stdio.h>

long Calculate_fact(int Number)
{
  if (Number == 0 || Number == 1)
    return 1;
  else
    return Number * Calculate_fact(Number - 1);
}

int Krishnamurthy_Number(int Number)
{
  int rem, Sum = 0;
  long fact;
  for (; Number > 0; Number = Number / 10)
  {
    fact = 1;
    rem = Number % 10;
    fact = Calculate_fact(rem);
    Sum = Sum + fact;
  }
  return Sum;
}

int main()
{
  int Number, Sum = 0, min, max;

  printf("Please Enter the min & max Krishnamurthy Number = ");
  scanf("%d %d", &min, &max);

  printf("The List of Krishnamurthy Numbers\n");
  for (Number = min; Number <= max; Number++)
  {
    Sum = Krishnamurthy_Number(Number);
    if (Number == Sum)
    {
      printf("%d  ", Number);
    }
      
  }

  printf("\n");
}

Please Enter the min & max Krishnamurthy Number = 1 100000
The List of Krishnamurthy Numbers
1  2  145  40585
