如何从char**获取char*

Question

我明白&用于引用对象的地址&char* = char**.反正是有扭转,这样我可以得到char*从char**？

所以我有:

char** str; //assigned to and memory allocated somewhere

printf ("%s", str); //here I want to print the string.

我该怎么做呢？

Answer 1

您可以使用取消引用运算符.

的引用操作符上的指针变量进行操作,并返回一个1-值等同于在指针地址的值.这称为"解除引用"指针.

char** str; //assigned to and memory allocated somewhere

printf ("%s", *str); //here I want to print the string.

Answer 2

取消引用str:

print ("%s", *str); /* assuming *str is null-terminated */
