4)Binary integer constant (base 2, the first digit is the most significant). The following variables are initialized to the same value: intd=42;into=052;intx=0x2a;intX=0X2A;intb=0b101010;// C23 The following variables are also initialized to the same value: ...
From the name we can see how straightforward it is: it’s basically put one bit (often the MSB) as the sign bit to represent sign and the remaining bits indicating the magnitude (or absolute value), e.g. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 binary | sign-magn | unsigned...
