谈计算机对'\0'和null的处理

#include <stdio.h>

int main()
{
char a = '\0';
char *p = NULL;

if (a)
{
printf(" '\0' is true\n");
}

if (p)
{
printf(" 'p' is true\n");
}

if (a==0)
{
printf(" '\\0' equals zero \n");
}

if (p==0)
{
printf(" Null equals zero\n");
}

//结论: '\\0' equals zero \n , Null equals zero

return 0;
}
