It is difficult and difficult to flip the binary position of C language !!!
Problem description: Write the function: unsigned int reverse_bit (unsigned int value); the value returned by this function is the value after the binary bit mode is flipped from left to right. For example, on a 32-bit machine, the value 25 contains the following: 00000000000000000000000000011001 after the flip: (2550136832) the result of the 10011000000000000000000000000000 program is returned: 2550136832 code implementation:

# Include <stdio. h> # include <math. h> unsigned int reverse_bit (unsigned int value) {int I = 0; unsigned int sum = 0; for (I = 0; I <32; I ++) {sum + = (value> I) & 1) * pow (2,31-i);} return sum;} int main () {unsigned int value = 25; // 00000000 00000000 00000000 00011001 int ret = reverse_bit (value); printf ("% u \ n", ret); return 0 ;}
