Is this a rigorous enough way to find the minimum size of an unsigned char?

int main()


{


int i=10;


unsigned char c=10,bc=0;


int TakingOut=1,msg=0;





bc=c--;


do {


msg=!TakingOut;


}while ((!msg)%26amp;%26amp;c%26lt;bc%26amp;%26amp;(bc=c--));





printf("The minimum size of unsigned char is %u.\n\n",bc);





system("PAUSE"); return 0;


}

What do you mean by the minimum size of an unsigned char?





Char is by default in most architectures (if not all modern ones) is 1 byte long.





Also, you can find the size of any type by using the sizeof operator.





sizeof(int) == 4 for example.





If you mean the range of unsigned char, then it should be 0 - 255 for unsigned char.
Reply:No, I'm afraid that it isn't.
