将整数数组转换为无符号字符数组

Question

例如，我在整数数组中存储了一个“位”

int a = {1,0,1,1} 

我如何才能将整数数组“位”转换为无符号字符“位”？

和互惠？

Answer 1

int int_array[] = {1, 0, 1, 1};
unsigned char uc_array[sizeof int_array / sizeof *int_array];
for (size_t i = 0; i != sizeof int_array / sizeof *int_array; ++i)
  uc_array[i] = int_array[i];

(您的示例代码有缺陷:标量变量的初始值设定项太多)
