练习：数组元素的运用和字符串的储存

#include <stdio.h>

int main(void)

{
char my[ ]="love";
printf("my %s",my);
return 0;
}

#include <stdio.h>
int main(void)
{
char my[7];
my[0]='l';
my[1]='o';
my[2]='v';
my[3]='e';
my[4]='\0';
printf("my %s",my);
return 0;
}

#include <stdio.h>
int main(void)
{
char my[7]="love";
printf("字节数%d\n",sizeof(my)); //求字节运算-sizeof(my),%d
printf("元素数%d\n",sizeof(my[0])); //求元素运算-sizeof(my[0]),%d
printf("my %s\n",my);
my[2]=0;
/*0,1,2,3,5
  l o v e 0
  l o 0 0 0
  当数组中有‘0’出现的话，就相当于编译器以为‘0’是数组结束符*/
printf("my %s",my);

return 0;
}
