C

Years I learned C [ch02]: Macro, struct, typedef, ch02typedef C language compilation process: Preprocessing Compile Assembly LinkThere are three situations in Preprocessing: File Inclusion (# include) Conditional compilation (# if, # ifndef, #

Replication of complex linked lists in c Language // Header file # pragma oncetypedef int DataType; typedef struct ComplexNode {DataType _ data; // data struct ComplexNode * _ next; // pointer to next node struct ComplexNode * _ random; // point to

Objective-C Block Block Code block is a feature of OC. In addition to executable code, it may also contain automatic variable binding (stack) or memory hosting (HEAP ). Therefore, a block maintains a state set (data) and can be executed at any time.

Simulate user logon in C language and only log on three times Include # include int main () {// defines the reserved password char key [] = "123456"; char input [10]; int I = 0; // enter the password and password for (I = 0; I  

Use C language to output Diamond (13 rows) # Include int main () {int I, j; // first pipe the first 7 rows for (I = 1; I  

Write a program using C language to output each bit of a number (multiple methods)First: # Include int main () {int zheng, I; int m = 0; int yu [10]; int count = 0; scanf ("% d", & m ); zheng = m; for (I = 0; I  Second: # Include int main ()

C language, c1. Fast Sorting Algorithm 1 # include 2 3 struct node 4 {5 int key; 6}; 7 typedef struct node DataType; 8 9 int Qukpass_sort (DataType Ar [], int s, int t ); 10 int Quk_Sort (DataType Ar [], int s, int t); 11 12 int main (void) 13 {14 1

Calculate the factorial and sum of n using C language (multiple methods)Calculate the factorial of a certain number: # Include int main () {int n, I; scanf ("% d", & n); for (I = n-1; I> 0; I --) {n = n * I;} printf ("% d", n); return 0 ;}

C language, cI. Task One class has m girls and n boys (m is not equal to n). Now we have a dance. The boys and girls sat on the chairs on both sides of the dance floor. At the beginning of each song, one of the boys and the girls danced together,

C language pointer, C language pointer Pointers are very important data types in C language. What are pointers? The pointer type is a variable used to store the variable address, pointing to a variable. Common pointer format: * pointer variable

[C Language] implements the itoa (int n, char s []) function, converts the integer n to the corresponding string, and saves it to s. # Include static int I = 0; // defines the global variable I as the subscript of the array s [] int itoa (int n,

C language-three solutions for String LengthProblem: three solutions for finding a string I. Counting Methods #include#includeint my_strlen( char* str){ int count=0; while (*str) { count++; str++; } return count;}int

C language-simulate database functions strcpy, strcat, strcmp1. Database strcpy function, copy a string to another string #include#includechar* my_srtcpy( char *srt, char*src){ assert(srt); assert(src); char *tmp = src; while (*src++ =

[C Language] extract substring Compile a function that extracts a substring from a string. The function is prototype: int substr (char dst [], char src [], int start, int len) {}. The target is: start from the start position of the src array and

Interesting C language appletsDetermine the output content of the following program: #define _CRT_SECURE_NO_WARNINGS 1#include #include int main() { int i=43; printf("%d\n",printf("%d",printf("%d",i))); system("pause"); return 0;

Small games implemented in C Language # Include void menu () {printf ("*************************** \ n "); printf ("************ 1> start ********** \ n "); printf ("************ 2> exit ********** \ n "); printf ("*************************** \ n")

C language: Write a function, strcpy, dest, src, which extracts a substring from a string. # include # include # include // chain access char * my_strcpy (char * dest, const char * src) {char * ret = dest; assert (src! = NULL); assert (dest! =

Use C language to calculate a simple mathematical formula // Calculate the sum of the first five items of Sn = a + aa + aaa + aaaa + aaaaa, a is a number // such as 2 + 22 + 222 + 2222 + 22222 # include int main () {int num = 0; int n = 0; int sum

[C Language] compile a half lookup Function # Include int zheban (int x, int arr [], int left, int right) {while (left arr [mid]) {left = mid + 1 ;} else {return arr [mid] ;}} return-1 ;}int main () {int arr [8] = {1, 2, 3, 4, 5, 6, 7, 8 }; int
