Bit shift in cpp11 Supporting tagline

今天复习一下 c++ 里面的位移操作

#include <iostream>
void uc_shift(unsigned char uc)
{
	uc = uc << 1;
	std::cout<<(unsigned int )uc<<std::endl;
}
int main(int argc, char const *argv[])
{
	unsigned char uc0 {255}; // 11111111
	uc_shift(uc0);			 // 11111110
 
	uc0 = {252};		 	 // 11111100
	uc_shift(uc0);			 // 11111000

}
