char c=0XFF41; //the lower 8 bits hex code 41 is assigned to c. cout<<c; //c is character A

Question

这两句在C++里处理是什么意思？c的值是怎么来的？
char c=0XFF41; //the lower 8 bits hex code 41 is assigned to c.

cout<<c; //c is character A

Answer 1

A这个字符的asic码就是0x41，c字符占用2字节，前面的ff没意义，可以直接进行16进制赋值的，下面的程序你去运行，看看结果吧
#include "stdio.h"
int main()
{
char c='A';
printf("%x",c);
putchar('\n');
return 0;
}
