conditional statement
Using the
conditional statement, print the season of year. The months with
numbers are
given below:
·
12, 1 è 2 – winter,
·
3, 4 è 5 – spring,
·
6, 7 è 8 – summer,
·
9, 10 è 11 – autumn.
Algorithm realization
Read
the input data.
scanf("%d",&n);
Print the aswer.
if ((n == 12) || (n == 1) || (n == 2))
printf("Winter\n"); else
if ((n >= 3) && (n <= 5))
printf("Spring\n"); else
if ((n >= 6) && (n <= 8))
printf("Summer\n"); else printf("Autumn\n");
Algorithm realization – optimal
Reduce the number of conditions.
#include <stdio.h>
int n;
int main(void)
{
scanf("%d",&n);
if ((n == 12)
|| (n == 1) || (n == 2)) printf("Winter\n");
else
if (n <=
5) printf("Spring\n"); else
if (n <=
8) printf("Summer\n"); else
printf("Autumn\n");
return 0;
}
Algorithm realization – switch
#include <stdio.h>
int n;
int main(void)
{
scanf("%d",
&n);
switch (n)
{
case 1:
case 2:
case 12:
puts("Winter");
