关于数组

关于数组

a.c:38: 错误：将‘char’赋值给‘char [1]’时类型不兼容 

数组与指针的差别.
delete [] p 
delete  p 
如何看出差别呢?
delete 如何知道我删除的是一个数字?


等价数组确实指针等价. 
 
char a[26];
a+3 ='a' ; 
a[3] ='a' ; 

打印
%c  a  不能正常输出,因为a的内容是数组首地址.
%d  a  输出数组a的内存地址.
%s  a  输出a的内容,字符串正常.

void foo(char c);     // a function which takes a char as a parameter

void bar(char c[1]);  // a function which takes a char* as a parameter

void baz(char c[12]); // also a function which takes a char* as a parameter

In bar and baz,  c  never has array type - it looks like an array type, but it isn't, it's just a fancy special-case syntax with the same meaning as  char *c . Which is why I put the quotation marks on "use" - you aren't really using  char[1]  at all, it just looks like it.
