水仙花數(shù)是指一個3位數(shù),其各位數(shù)字的立方和等于該數(shù)本身。下面是使用函數(shù)來求解水仙花數(shù)的示例代碼:
#include <stdio.h>
int isArmstrongNumber(int num) {
int originalNum, remainder, result = 0;
originalNum = num;
while (originalNum != 0) {
remainder = originalNum % 10;
result += remainder * remainder * remainder;
originalNum /= 10;
}
if (result == num) {
return 1;
} else {
return 0;
}
}
int main() {
int num;
printf("請輸入一個3位數(shù):");
scanf("%d", &num);
if (isArmstrongNumber(num)) {
printf("%d 是水仙花數(shù)\n", num);
} else {
printf("%d 不是水仙花數(shù)\n", num);
}
return 0;
}
運行程序后,輸入一個3位數(shù),程序會判斷該數(shù)是否為水仙花數(shù)并輸出結(jié)果。
