若statement內容相同,可合併case (不同case:需以 空白 分隔)
#include <stdio.h> main() { int year, month, days; scanf("%d", &year); scanf("%d", &month); switch (month) { case 1: case 3: case 5: case 7: case 8: case 10: case 12: days = 31; break; case 4: case 6: case 9: case 11: days = 30; break; case 2: if ((year % 400 == 0) || ((year % 4 == 0) && (year % 100 != 0))) days = 29; else days = 28; break; default: days = 0; } printf("%d\n", days); } |
