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.参考:
