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:

   printf("格式化字符串", 变量1, 变量2, ...);

   Copy after login

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

   printf("换行输出\n"); // 输出 "换行输出" 并换行

   Copy after login

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:

   putchar(10); // 换行输出

   Copy after login

Usage Demonstration

The following code snippet demonstrates these two newline outputs Method:

#include  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; }

Output result:

换行输出 1 换行输出 2
