C + +: Small-end mode and forced data type conversions

Source: Internet
Author: User

1. Start with a question

Problems with C + + data type conversions

#include <iostream.h>  
void Main ()  
{  
    int i=0xb62;  
    char c;  
    c=i;  
    cout<<c<<endl;  
}

Why is the output of B here?

2. Check the CPU byte sequence of the computer we use first

Version one (with a problem, the result is 34 in any case, it does not indicate whether 34 is a high address or a low address)

Version two (according to shineyan1991 's comments after the change, thanks to shineyan1991 's suggestion)

The above figure shows that the byte order of the CPU is a small-end pattern.
