练习：a[];sizeof;数组

#include <stdio.h>
int main(void)
{
int a[8]={1,3,5,7,9,2,4,6};
printf("%d,%d,%d,%d,%d,%d,%d,%d",
a[0],a[1],a[2],a[3],a[4],a[5],a[6],a[7]);
return 0;
}

 

 

 

#include <stdio.h>
int main(void)
{
int a[]={1,2,3,100};
printf("数组a占用了%d个字节\n数组a占用了%d个元素\n",sizeof(a),sizeof(a)/sizeof(a[0]));
return 0;
}
