Struktur-Einleitungsprogramme in C
Um einen Satz Ausgangswerte für die Struktur zur Verfügung zu stellen, kann Initialisers der Erklärungaussage hinzugefügt werden. Während Monate mit 1 beginnen, aber Reihen mit null in C beginnen, ist ein Extraelement in der Position null, die Trödel genannt wird, im folgenden Beispiel benutzt worden.
#include <stdio.h>
#include <string.h>
struct month
{
char *name;
char *abbreviation;
int days;
} month_details[] =
{
"Junk", "Junk", 0,
"January", "Jan", 31,
"February", "Feb", 28,
"March", "Mar", 31,
"April", "Apr", 30,
"May", "May", 31,
"June", "Jun", 30,
"July", "Jul", 31,
"August", "Aug", 31,
"September", "Sep", 30,
"October", "Oct", 31,
"November", "Nov", 30,
"December", "Dec", 31
};
int main()
{
int counter;
for (counter=1; counter<=12; counter++)
printf("%s is abbreviated as %s and has %d days\n",
month_details[counter].name,
month_details[counter].abbreviation,
month_details[counter].days);
return 0;
}
Und der Ausgang wird angezeigt, wie folgt:
January is abbreviated as Jan and has 31 days
February is abbreviated as Feb and has 28 days
March is abbreviated as Mar and has 31 days
April is abbreviated as Apr and has 30 days
May is abbreviated as May and has 31 days
June is abbreviated as Jun and has 30 days
July is abbreviated as Jul and has 31 days
August is abbreviated as Aug and has 31 days
September is abbreviated as Sep and has 30 days
October is abbreviated as Oct and has 31 days
November is abbreviated as Nov and has 30 days
December is abbreviated as Dec and has 31 days |
