Since this question is returned by searches for “how to read a string with scanf”, it might be appropriate to point out that this question is about ways to pass the pointer to the buffer to scanf, and both the question and the accepted answer focus on that, and omit the critically important restrictions for maximum input length that should be used in real code (but are besides the point for

C program – Read string with spaces using scanf() function, here we are writing how to read a complete string with multiple spaces using scanf() and how to print? Read string with spaces using scanf() function in C programming language – In this program we are going to explain how we can take input of a string with spaces?

c Character The next character. If a width other than 1 is specified, the function reads exactly width characters and stores them in the successive locations of the array passed as argument. No null character is appended at the end. s String of characters

scanf format string (which stands for “scan formatted”) refers to a control parameter used by a class of functions in the string-processing libraries of various programming languages.The format string specifies a method for reading a string into an arbitrary number of varied data type parameter(s). parameter(s).

scanf函数称为格式输入函数,即按用户指定的格式从键盘上把数据输入到指定的变量之中。 scanf函数的一般形式 scanf函数是一个标准库函数,它的函数原型在头文件stdio.h中,与printf函数相同,C语言也允许在使用scanf函数之前不必包含stdio.h文件。 scanf函数

學習 C 的過程中,通常是從主控台,也就是文字模式下開始,為了與程式互動,在主控台下輸出程式執行結果,或是從主控台取得使用者的輸入資料是基本需求,在 C 中標準輸入輸出是由 stdio.h 提供,這也就是為何要在程式的一開頭總是加上:

Reading String with spaces by using scanf Note that – scanf with %s accepts only String which does not contain whitespaces (blanks/space) C Supports the ‘ special Edit set Conversion Code ‘ , by using this method we can accept the line of String with spaces

附加参数– 根据不同的 format 字符串,函数可能需要一系列的附加参数,每个参数包含了一个要被插入的值,替换了 format 参数中指定的每个 % 标签。参数的个数应与 % 标签的个数相同。 返回值 如果成功,该函数返回成功匹配和赋值的个数。如果到达文件末尾或发生读错误,则返回 EOF。
