# 2.5 Code block

For programmers, this function is essential , There are two ways to insert code , One is to use indentation （tab）, The other is to use English "`" Symbol （ Generally in esc The next one ） Package code

- (1) Code block ： Indent four spaces or a tab . The effect is as follows ：

- (2) Inline

- If a line needs code , Only need to use "`" Just wrap it in inverted quotation marks

- This is an example `printf(hello world\n);`

- (3) Multi line code block and syntax highlighting ： Wrap the first and last lines of the code block that needs to be highlighted with three SLR symbols ``` Keep up c perhaps python Language like that

```c

#include <stdio.h>

int main()

{

int i, n;

printf(" Please enter the number of characters ：");

scanf("%d", &n);

char a[n+1];

printf(" Please start entering characters ：");

getchar();

for (i = 0; i < n; i++)

{

scanf("%c", &a[i]);

}

a[n] = '\0';

printf(" The string you entered is %s\n", a);

return 0;

}

```

- (4) The code block contains html Code

- In the code block ,&、< and > Will automatically convert to html Entity , In this way, you just need to html Copy and paste the original code

- Be careful ： It is not supported in the code block of the short book html

<table>

<tr>

<th rowspan='2'> Duty officer </th>

<th> Monday </th>

<th> Tuesday </th>

<th> Wednesday </th>

</tr>

<tr>

<td> Li Qiang </td>

<td> Zhang Ming </td>

<td> Wang Ping </td>

</tr>

</table>

# 2.7 list

2. There are sequence items demonstration

- # List text

- > The list contains quoted text

- （ Use split lines in the list ）

- ---

- I don't quite understand some precautions for writing code blocks in the list

```c

printf("hello world\n")

```
