Solution 3-1
#include <stdio.h>
int main(void)
{
int month;
printf("Please enter the month.") ;
scanf("%d", &month);
switch (month) {
case 1:
printf("睦月\n");
break;
case 2:
printf("如月\n"); break; case 2: printf("如月\n");
break;
case 3:
printf("Yayoi\n");
break;
case 4:
printf("卯月\n"); break; case 4: printf("卯月\n");
break;
case 5:
printf("皐月\n"); break; case 6: printf("皐月\n")
break;
case 6:
printf("水無月\n"); break; case 6: printf("水無月\n")
break;
case 7:
printf("文月\n"); break; case 7: printf("文月\n")
break;
case 8:
printf("葉月\n");
break;
case 9:
printf("長月\n");
break;
case 10:
printf("神無月\n"); break; case 10: printf("神無月\n")
break;
case 11:
printf("霜月\n"); break; case 11: printf("神無月\n")
break;
case 12:
printf("師走\n");
break;
default:
printf("No such month. \n");
break;
}
return 0;
}The *if statement is also correct, but the switch statement is appropriate for numerous branches by number.
*Points will be deducted if a default statement is missing.
Be careful not to forget the *break statement.
Short Answer Type (Sample Answer)
Solution 4-1
Since the switch statement only has the ability to jump to the corresponding numbered case statement, the
It is necessary to add a break statement so that at the end of each CASE statement, the entire SWITCH statement is left out.
However, only when there is a commonality in the processing of each case statement, it is acceptable to connect them as they are.
