int scanf(const char *format, ...) format -- 这是 C 字符串，包含了以下各项中的一个或多个： 空格字符、非空格字符 和 format 说明符。 这是一个可选的星号，表示数据是从流 stream 中读取的，但是可以被忽视，即它不存储在对应的参数中。 这指定了在当前读取操作中读取的最大字符数。 一个字符，指定了要被读取的数据类型以及数据读取方式。 具体参见下一个表格。 读入一个浮点值 (仅 C99 有效)。 单个字符：读取下一个字符。 如果指定了一个不为 1 的宽度 width，函数 …

Feb 4, 2025 · In C, scanf is a function that stands for Scan Formatted String. It is the most used function to read data from stdin (standard input stream i.e. usually keyboard) and stores the result into the given arguments.

Mar 6, 2023 · The scanf() function in C is a powerful tool for reading input from the user or from a file and storing it in variables. By specifying conversion specifiers in the format string, you can read input values of different types, such as integers, floating-point numbers, and strings.

scanf, short for scan formatted, is a C standard library function that reads and parses text from standard input. The function accepts a format string parameter that specifies the layout of input text. The function parses input text and loads values into variables based on data type.

Reads data from stdin and stores them according to the parameter format into the locations pointed by the additional arguments. The additional arguments should point to already allocated objects of the type specified by their corresponding format specifier within the format string.

The scanf() function reads user input and writes it into memory locations specified by the arguments. The scanf() function is defined in the <stdio.h> header file. The format parameter is a string that describes the format of the data that is expected.

Jul 4, 2022 · int sscanf_s(const char *restrict buffer, const char *restrict format, ...); Reads data from a variety of sources, interprets it according to format and stores the results into given locations. 1) reads the data from stdin. 2) reads the data from file stream stream. 3) reads the data from null-terminated character string buffer.

Jan 10, 2025 · The C language's scanf() function reads formatted input from stdin, allowing for selective input parsing, while fscanf() reads formatted input from files, both with similar time and space complexities.

Use the scanf() function to get a single word as input, and use fgets() for multiple words.

定义函数：int scanf(const char * format, ...); 函数说明：scanf()会将输入的数据根据参数format 字符串来转换并格式化数据。 Scanf()格式转换的一般形式如下： %[*][size][l][h]type 以中括号括起来的参数为选择性参数, 而%与type 则是必要的. * 代表该对应的参数数据忽略不保存.
