Problem Description:
There are 10 kinds of people in the world, one knows the binary system, one does not understand. So you know the binary expression of two int32 integers m and n, how many bits are different?
Enter an example:
1999 2299
Output Example:
7
My Code:
/** * The number of
different digits in the binary of two numbers
* @param m
* @param n
* @return Returns the number of different digits/public
static int Countbit
fibs number of digits

Description
The generalized Fibonacci sequence is defined as follows:
R0=a; R1= b; rn= uRn-1 + vRn-2 (n >= 3) Here a,b,u,v are real numbers, called RN for the generalized Fibonacci sequence. Now let you calculate the number of bits of the generalized Fibonacci sequence.
Enter a number of integers (which can be positive, negative, or 0) to output the last 3 bits of their product. These integers are mixed with a string of uppercase letters, and your program should ignore them. Tip: Try to enter a string when executing scanf ("%d").
Problem Solving Ideas:Find out the number multiplier in the string, note the end of the string in the calculation process and overflow the exception.

Optimization of Algorithm for counting the number of 1 in binary bits in C LanguageTo count the number of 1 in an integer binary:
Int one (int m) {int count = 0; while (m! = 0) {if (m % 2 = 1) // perform the modulo 2 Division 2 one-digit statistics {count ++;} m/= 2 ;}}
Or the following operations
Int two (int m) {int count = 0; while (m! = 0) {count + = m 1; // The principle for calculating the number of statistical items in 1 is the same as that

Windows bitmap and attaching the bitmap to the object.
Attributes
Getbitmap
FillsBitmapStructure with information about the bitmap.
Operator hbitmap
Returns the Windows handle attached toCbitmapObject.
Operations
Fromhandle
Returns a pointer toCbitmapObject when given a handle to a WindowsHbitmapBitmap.
Getbitmapbits
Copies the bits of the specified bitmap into the specified buffer.
The problem was solved by DP at the beginning, but it was wrong to think about it, because such bit operations could not obtain the optimal solution until the last computation, that is, there was no optimal sub-structure.
First, when a and B perform operations, we analyze every bit on the 64-bit. We know that the and ^ operations always generate 0, so we can always make the 32-bit value equal to 0 for the two 64-bit numbers. If we calculate the number X and C, we will directly convert X C, tho
