C语言实现水仙花数判断与累加 - 详解代码及优化

#include <stdio.h>

int sxh() { int x, n = 0;

for(x=100;x<=999;x++) { int temp = x; int sum = 0; while(temp > 0) { int digit = temp % 10; sum += digit * digit * digit; temp /= 10; }

if(sum == x) {
  printf('%d ',x);
  n += x;
}

}

return n; }

int main() { printf("\n三位水仙花数之和为：\n%d\n",sxh()); return 0; }
