we have used different functions used to read a line. The built-in function in c programming is getline() which is used for reading the lines from the stdin. But we can also use other functions like
用整数n表示。显然，这个整数被初始化为零（在C中不确定），所以缓冲区的第四个字节（不是由read()...
/* Read formatted input from stdin.This function is a possible cancellation point and therefore notmarked with __THROW. */externintscanf(constchar*__restrict__format,...)__wur; 使用Mac或Linux的同学,在终端上输入man scanf回车即可学习scanf函数的用法。我们可以看到注释上说明,scanf从标准输入stdin输入...

The scanf() function reads input from the standard input stream stdin, fscanf() reads input from the stream pointer stream, and sscanf() reads its input from the character string pointed to by str.The vfscanf() function is analogous to vfprintf(3) and reads input from the stream pointer ...
