C 新行


新行

要插入新行,可以使用 \n 字符

例子

#include <stdio.h>

int main() {
  printf("Hello World!\n");
  printf("I am learning C.");
  return 0;
}
自己试试 »

你也可以使用单个 printf() 函数输出多行。但是,这会使代码更难阅读

例子

#include <stdio.h>

int main() {
  printf("Hello World!\nI am learning C.\nAnd it is awesome!");
  return 0;
}
自己试试 »

提示: 两个 \n 字符彼此相邻将创建一个空行

例子

#include <stdio.h>

int main() {
  printf("Hello World!\n\n");
  printf("I am learning C.");
  return 0;
}
自己试试 »

\n 到底是什么?

换行符 (\n) 被称为 转义序列,它迫使光标将位置更改为屏幕上下一行的开头。这将导致新行。

其他有效转义序列的示例是

转义序列 描述 试试
\t 创建一个水平制表符 试试
\\ 插入反斜杠字符 (\) 试试
\" 插入双引号字符 试试
