C语言中scanf的操作代码

scanf真的是骚呀，在这儿占个坑，记录一下scanf的骚操作

// Declare a variable named 'input_string' to hold our input.
char input_string[105]; 
// Read a full line of input from stdin and save it to our variable, input_string.
//%[]==%s,input a string,and '^' means opposite or negative,so '^\n' means getting everything but'\n'
scanf("%[^\n]", input_string);
