【C语言位运算的应用】如何按bit位翻转一个无符号整型

#include <stdio.h>//按位翻转一个无符号整形
unsigned int reverse_bit(unsigned int value)
{
unsigned int num = 0;
int i = 0;
for (i = 1; i < 32; i++)
{
num += value & 1;
num <<= 1;
value >>= 1;
}
return num;
}

int main()
{
unsigned int num = 25;
printf("%u", reverse_bit(num));
system("pause");
return 0;
}
