什么是按位异？
#include <stdio.h>int main(void)
{
unsigned long int number, num1, num2, mask;
int i;
char str[33];
printf("Please input num1 and num2 : ");
scanf("%lu %lu", &num1, &num2);
/*********Found************/
mask = __________________;
number = num1 ^ num2;
for(i=0; i<32; i++)
{
/*********Found************/
str[i] = __________________;
mask >>= 1;
}
str[32] = '\0';
printf("%lu ^ %lu = %s\n", num1, num2, str);
return 0;
}
