普通版：

#include<stdio.h>
int main() {
	int get_leftvalue = 0, get_rightvalue = 0;
	scanf("%d %d", &get_leftvalue, &get_rightvalue);
	for (int i = get_leftvalue; i <= get_rightvalue; i++) {
		int thousand_bit = i/1000;
		int hundredth_bit = (i/100)%10;
		int ten_bit = (i/10)%10;
		int bit = i%10;
		if (thousand_bit * thousand_bit * thousand_bit * thousand_bit + hundredth_bit * hundredth_bit * hundredth_bit * hundredth_bit+ ten_bit * ten_bit * ten_bit * ten_bit + bit * bit * bit * bit== i  && thousand_bit < 10) {
			printf("%d ", i);
		}
	}
	return 0;
}

函数引用版：

#include<stdio.h>
#include<math.h>
int func_RosaNum(int left_value,int right_value) {
	for (int i = left_value; i <= right_value; i++) {
		int thousand_bit = i/1000;
		int hundredth_bit = (i/100)%10;
		int ten_bit = (i/10)%10;
		int bit = i%10;
		int sum = pow(thousand_bit, 4) + pow(hundredth_bit,4) + pow(ten_bit,4) + pow(bit,4);
		if (sum == i && thousand_bit < 10) {
			printf("%d ", i);
		}
		//printf("%d %d %d %d\n", thousand_bit, hundredth_bit, ten_bit, bit);

	}
}

int main() {
	int get_leftvalue = 0, get_rightvalue = 0;
	scanf("%d %d", &get_leftvalue, &get_rightvalue);
	func_RosaNum(get_leftvalue, get_rightvalue);
	return 0;
}
