Question

c语言中循环右移怎么实现？程序应该怎么写

Answer 1

unsigned char crol(unsigned char c,unsigned b)
{ //左移
unsigned char left;left=c<<b;
unsigned char right;right=c>>( sizeof (unsigned char )-b) ;
return left|right;

}
unsigned char cror(unsigned char c,unsigned b)
{ //右移
unsigned char right;
right =c>>b;
unsigned char left ;
left=c<<( sizeof (unsigned char )-b) ;
return left|right;

}

Answer 2

右移2位
int c;
c=c>>2;
或
c>>=2;
