转换INT，双成char数组中的C或目标C [英] Converting int, double to char array in C or Objective C

问题描述

我要转换的int char数组和双到字符数组。任何方式在C或目标C这样做的。

I want to convert int to char array and double to char array. Any way of doing this in C or Objective C.

推荐答案

如果你想治疗的人数为字符的数组，你可以把地址和投指针：

If you want to treat the number as an array of char, you can take the address and cast the pointer:

int i;
double d;
char * ic = (char *) &i;
char * dc = (char *) &d;

然后 IC 和 DC 是指向字符 。他们不是零结尾的，所以你不能把它们作为字符串，但它们可以被用来作为数组。

then ic and dc are pointers to char. They aren't zero-terminated, so you can't use them as strings, but they can be used as arrays.
