How to wrap output in c language program

In C language, there are two methods for newline output: using the printf() function and using the newline escape sequence \n. Use the putchar() function and use ASCII code 10 for the newline character.

How to use C language program to wrap output

In C language, wrap output can realize the end of text line Wrap, that is, create a new line. There are two commonly used methods to achieve newline output:

1. printf() function

   printf() function The format is:

   <code class="c">printf("格式化字符串", 变量1, 变量2, ...);</code>

   To use the printf() function for newline output, you can use the newline escape sequence \n:

   <code class="c">printf("换行输出\n"); // 输出 "换行输出" 并换行</code>

2. putchar() function

   putchar() The function outputs a single character to standard output. To achieve newline output, you can use the newline ASCII code 10:

   <code class="c">putchar(10); // 换行输出</code>

Usage Demonstration

The following code snippet demonstrates these two newline outputs Method:

<code class="c">#include <stdio.h>

int main() {
    // 使用 printf() 函数换行输出
    printf("换行输出 1\n");

    // 使用 putchar() 函数换行输出
    putchar(10);
    printf("换行输出 2");

    return 0;
}</code>

Output result:

<code>换行输出 1

换行输出 2</code>
