## 程式語言學習網站小整理
[TOC]
## Github
資工相關學生都該去辦一個
最大程式碼開源網站
https://github.com/sapt36
(歡迎追蹤，裡面是我大學在學期間曾打過的程式所有內容)
## Markdown
常用語法整理：

## Java
類別與建構式：
https://ithelp.ithome.com.tw/articles/10236606
Static 執行順序：
https://juejin.cn/post/7000735799692132389
https://www.itread01.com/content/1541746087.html
```gherkin=
public class TestClass {
public static void main(String[] args) {
// TODO Auto-generated method stub
ParentClass pa = new ParentClass();
}
}
public class ParentClass {
static int num = 0;
String name = "A";
static String name2 = "B";
static ParentClass parentClass = new ParentClass();
ParentClass(){
System.out.println("建構函式1");
}
{
System.out.println("name1:" + name);
System.out.println("區塊1");
}
static {
num += 1;
System.out.println("name2:" + name2);
System.out.println("靜態初始化區塊" + num);
}
}
```
執行結果：
> name1:A
> 區塊1
> 建構函式1
> name2:B
> 靜態初始化區塊
> name1:A
> 區塊1
> 建構函式1
字串-->字串陣列 字串反轉：
https://www.delftstack.com/zh-tw/howto/java/how-to-reverse-an-int-array-in-java/
https://www.delftstack.com/zh-tw/howto/java/how-to-perform-string-to-string-array-conversion-in-java/
```gherkin=
import java.util.*;
public class Example3 {
public static void reverse(Integer x[]) {
Collections.reverse(Arrays.asList(x));
System.out.println(Arrays.asList(x));
}
public static void main(String[] args) {
Integer [] arr = {15, 25, 35, 45, 55};
reverse(arr);
}
}
```
輸出：
>[55, 45, 35, 25, 15]
HashMap
https://www.w3schools.com/java/java_hashmap.asp
```gherkin=
import java.util.HashMap;
public class Main {
public static void main(String[] args) {
HashMap<String, String> capitalCities = new HashMap<String, String>();
capitalCities.put("England", "London");
capitalCities.put("Germany", "Berlin");
capitalCities.put("Norway", "Oslo");
capitalCities.put("USA", "Washington DC");
System.out.println(capitalCities);
}
}
```
輸出：
>{USA=Washington DC, Norway=Oslo, England=London, Germany=Berlin}
## C
曾用過的所有相關網站：
https://openhome.cc/Gossip/CGossip/index.html
https://www.learn-c.org/en/Linked_lists
EX:
```gherkin=
#include <stdio.h>
int main(void) {
int n = 10;
printf("n 的值：%d\n", n);
printf("n 的位址：%p\n", &n);
return 0;
}
```
輸出：
>n 的值：10
n 的位址：0061FECC
經典範例：
https://programming.im.ncnu.edu.tw/C_Example.htm
https://www.w3schools.com/c/c_examples.php
```gherkin=
/* 程式功能：反射矩陣 */
#include <stdio.h>
void main(void) {
int a[9][9], b[9][9];
int i, j, m, n;
printf("請輸二維矩陣a的大小 m * n 的 m 與 n 值 : ");
scanf("%d %d",&m,&n);
printf("請輸入矩陣a的元素值(按列順序):\n");
for(i = 0; i < m; i++) {
for(j = 0; j < n; j++) {
scanf("%d",&a[i][j]); /*輸入矩陣a的元素值*/
b[i][n-j-1] = a[i][j]; /* b為矩陣a的反射矩陣*/
}
}
printf("\n");
printf("矩陣a的反射矩陣b如下:\n");
for(i = 0; i < m; i++) {
for(j = 0; j < n; j++) {
printf(" %d",b[i][j]);
}
printf("\n");
}
}
```
存取結構內屬性：
https://opensourcedoc.com/c-programming/struct/
```gherkin=
#include <assert.h>
typedef struct point_t point_t;
struct point_t {
double x;
double y;
};
int main(void)
{
point_t pt = {
.x = 3.0,
.y = 4.0
};
assert(pt.x == 3);
assert(pt.y == 4);
return 0;
}
```
