How to wrap lines in c language programming

In C language programming, you can use the following methods to wrap lines: escape character '\n' puts() function fputs() function fputc() function (print character by character, use character '\n' to print Line break)

How to use C language programming to wrap line

In C language programming, you can use the following Way to wrap:

1. Escape character '\n'

Using escape character '\n' is the most commonly used way to wrap line. It will move the cursor to the beginning of the next line. For example:

<code class="c">printf("第一行\n");
printf("第二行");</code>

Output:

<code>第一行
第二行</code>

2. puts() function

puts() function will print a string and wrap it automatically. For example:

<code class="c">puts("第一行");
puts("第二行");</code>

Output:

<code>第一行
第二行</code>

3. fputs() function

fputs() function is similar to puts() function, but it can Prints a string to the specified file. For example:

<code class="c">FILE *fp = fopen("output.txt", "w");
fputs("第一行\n", fp);
fputs("第二行", fp);
fclose(fp);</code>

Output (output.txt):

<code>第一行
第二行</code>

4. fputc() function

fputc() function can print character by character into the file. To print a newline character, use the character '\n'. For example:

<code class="c">FILE *fp = fopen("output.txt", "w");
fputc('第', fp);
fputc('一', fp);
fputc('行', fp);
fputc('\n', fp);
fputc('第', fp);
fputc('二', fp);
fputc('行', fp);
fclose(fp);</code>

Output (output.txt):

<code>第一行
第二行</code>
