二进制翻转

编写函数:
unsigned int reverse_bit(unsigned int value)
这个函数的返回值value的二进制位模式从左到右翻转后的值.
如:
在32位机器上25这个值包含下列各位:
0000000000000000011001
翻转后
1001100000000000000000
程序结果返回:2550136832

#include<stdio.h>
#include<stdlib.h>
unsigned int reverse_bit(unsigned int value){
	int ret = 0;
	int tem = 0;
	for (int i = 0; i < 32; i++){
		ret = ret << 1;
		tem = value & 1;
		value = value >> 1;
		ret = ret | tem;
	}
	return ret;
}
int main(){
	int ret = reverse_bit(25);
	printf("%u\n", ret);
	system("pause");
	return 0;
}
