;8 divided by 2 n-Th squareThese are some of the knowledge about the binary and bit operations, which may be a bit stiff and boring, let's look at an exercise in bitwise arithmetic to get a deeper look at some of the memory representations:1 //write a function to output the binary form of an integer in memory2#include 3 4 voidPrintbinary (intnumber);//make a declaration of a function5 6 intMain ()7 {8 9Printbinary ( the);//Call this function and assign a value ofTen return 0; One A

variable p points to the first element of an array of integers a[0], at this point I want to use this pointer variable p to access a[1] only need to p+1 that is * (p+1) can get a[1]Value. When we encode, we let p+1 and actually the memory address move 4 bytes (the memory space occupied by an integer data), that is to say p+i represents the memory address to move p+i*c (c is the number of bytes that p point

cannot assign a string constant to a character variable. There is no corresponding string variable in the C language. This is different from the basic language. However, you can use a character array to hold a string constant. Introduced in the chapter of the array.4. Character constants account for one byte of memory space. The number of bytes in a string constant is equal to the number of bytes in the string plus 1. Adds a byte that holds the chara

strsource to the string strdestination, including the null-value terminator. The return value is pointer strdestination.Note:1, "character array 1" must be written in the form of an array name, "String 2" can be a character array name, or it can be a string constant2. Copy to array 1 along with the ' \ ' after string3. You cannot assign a string constant or a character array directly to an array of characters (the same as an array of normal variables) using an assignment statement, but only wit

pointer variable points toConsiderations for pointer variables:1) What type of pointer variable can only point to a variable of the same type2) The pointer variable can be global or local Two related operators: : Take address operator; *: pointer operator (or "indirect access" operator). The address operator is provided in the C language to represent the address of the variable. Its general form is: variable name; If a represents

pointerA pointer function is a function whose return value is a pointer. In fact, there is no pointer function to say that only the return value is a function of a pointer or a function that is a pointer to a parameter.A function pointer is a pointer to a specific function. It is very useful in programming, can significantly reduce the amount of code and optimize the code structure , here is a simple usage example.1#include"stdio.h"2 3 #defineOK 14 5 intFUN1 (intnum)6 {7printf"The Fun1 value is
