C 将无符号整数以二进制形式显示输出

void binary_print(unsigned int value){
        unsigned int mask = 0xff000000;
        unsigned int shift = 256*256*256;
        unsigned int byte, byte_iterator, bit_iterator;

        for(byte_iterator=0; byte_iterator<4; byte_iterator++){
                byte = (value&mask) /shift;
                printf(" ");
                for(bit_iterator=0; bit_iterator<8; bit_iterator++){
                        if(byte&0x80)
                                printf("1");
                        else
                                printf("0");

                        byte *= 2;
                }
                mask /= 256;
                shift /= 256;
        }
}
