输出水仙花数的几类题

Posted 2020-12-21 srs7665

1、使用函数输出水仙花数

#include <stdio.h>
int narcissistic( int number );
void PrintN( int m, int n );
int main()
{
int m, n;

scanf("%d %d", &m, &n);
if ( narcissistic(m) ) printf("%d is a narcissistic number ", m);
PrintN(m, n);
if ( narcissistic(n) ) printf("%d is a narcissistic number ", n);

return 0;
}

int narcissistic( int number )
{
int a,b,c,d,e,f,g;
a=number%10;
b=number%100/10;
c=number/100;
d=number%10;
e=number%100/10;
f=number/100%10;
g=number/1000;
if(number==a*a*a+b*b*b+c*c*c||number==d*d*d*d+e*e*e*e+f*f*f*f+g*g*g*g)
{
return 1;
}else
return 0;
}

void PrintN( int m, int n )
{
for(int number=m+1;number<n;number++)
{
if(narcissistic(number)==1)
{
printf("%d ",number);
}
}
}

2、输出1-1000的水仙花数

#include<stdio.h>
int main(void){
int i,a,b,c;
for(i=1;i<=1000;i++){
a=i%10;
b=i/10%10;
c=i/100;
if(i=a*a*a+b*b*b+c*c*c)
printf("%d ",i);
}
return 0;
}
