用 C 判斷給定年份是否是閏年的程式
閏年有 366 天,而普通年份有 365 天,這項任務是透過程式檢查指定的年份是否是閏年。
判斷方法是檢查年份是否能被 400 或 4 整除,但如果數字不能被這兩個數字之一整除,那麼它將是普通年。
示例
Input-: year=2000 Output-: 2000 is a Leap Year Input-: year=101 Output-: 101 is not a Leap year
演算法
Start Step 1 -> declare function bool to check if year if a leap year or not bool check(int year) IF year % 400 = 0 || year%4 = 0 return true End Else return false End Step 2 -> In main() Declare variable as int year = 2000 Set check(year)? printf("%d is a Leap Year",year): printf("%d is not a Leap Year",year) Set year = 10 Set check(year)? printf("%d is a Leap Year",year): printf("
%d is not a Leap Year",year); Stop
示例
#include <stdio.h> #include <stdbool.h> //bool to check if year if a leap year or not bool check(int year){ // If a year is multiple of 400 or multiple of 4 then it is a leap year if (year % 400 == 0 || year%4 == 0) return true; else return false; } int main(){ int year = 2000; check(year)? printf("%d is a Leap Year",year): printf("%d is not a Leap Year",year); year = 101; check(year)? printf("%d is a Leap Year",year): printf("
%d is not a Leap Year",year); return 0; }
輸出
2000 is a Leap Year 101 is not a Leap Year
