`%c` is used to input character input for `char` variable type.There are different format specifiers for different variable types like below. The format should be the same as the given variable. Format specifiers are used to specifying the input data format which will be set for the given variable. scanf() Function Format Specifiersīefore starting the scanf() example we will provide the format specifiers. If there is an error like matching failure, reading error or reach the end of file the return value will be less than zero which value is related to the error type. If the scanf() function is completed successfully the return value will be the input parameter count.

The scanf() function will return an integer value which is not related to the input value. `VARIABLE1`, `VARIABLE2`, … are the variable name in which value will be set from the user input.`const char *FORMAT` is the format specifier of the input.This will provide the status of the reading operation. `int` is the return data type which is an integer after the reading input data.int scanf(const char *FORMAT, VARIABLE1, VAARIABLE2. For single-parameter, only VARIABLE1 will be specified.

We can also read multiple parameters with a single scanf() function. It has the following syntax and parameter meaning. scanf() Function SyntaxĪs a function scanf() accepts different parameters. The scanf() function is provided by the stdio.h library or header. The standard input can be also called as stdin in C and C++ terminology. The input data can be read in different formats by using format specifiers. scanf() function can read different data types and assign the data into different variable types. I will briefly introduce someĪ regular expression is a pattern that matches various text strings.Scanf() function is used to read input from the console or standard input of the application in C and C++ programming language. Understanding of regular expressions and Regex is essential.

So, I said, "I can'tįind one, but you can write something using regular expressions." Background

Know." After looking around I didn't find such a method. A friend asked me if there is a scanf method in.
