Convert integer array to unsigned char array

Question

I have storage a "bits" in integer array for example

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

How I will be able to convert the integer array "bits" into unsigned char "bits"?

and reciprocal?

not clear for me. Do you want to convert {1,0,1,1} to unsigned char e.g, unsigned char x = 1011; or its binary representation? — Jack

Your sample shouldn't compile without a severe warning, if at all. — Jens Gustedt

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];

(Your sample code is flawed: it has too many initializers for a scalar variable)

"Your sample code is flawed: it has too many initializers for a scalar variable" not understand, why is wrong?

@Juan: Because it should be int a[].
