cの構造初期設定装置
構造に一組の初期値を提供するためには、Initialisersは宣言の声明に加えられるかもしれない。 月が1時で始まるが、配列がで0点規正するcを始まると同時に、がらくたと呼ばれる位置次の例でゼロの余分要素は使用された。
#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;
}
そして出力は次の通り表示される:
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
