What is the equivalent of cin in C language?

In C, the cin function is used to read data from standard input (usually the keyboard). It is very similar to the scanf function in C language.

Detailed comparison:

Features	C cin	C scanf
Function name	cin	scanf
Input source	Standard input	Standard input
Data type	Stream object	Format string
Format specifier	Operator	% Conversion specifier
Error handling	Throw exception	Return failure code

Usage example:

C ：

<code class="cpp">int num;
cin >> num;</code>

C：

<code class="c">int num;
scanf("%d", &num);</code>

Other differences:

• cin is a stream object that provides higher-level I/O operations.
• scanf requires a format string to specify the format of the input data, and cin uses the operator, which can Automatically detect data types.
• cin throws an exception to handle errors, while scanf returns a failure code.

Conclusion:

The cin function in C is equivalent to the scanf function in C language. Use For reading data from standard input. cin Provides higher-level I/O operations, using the operator to automatically detect data types and throw exceptions when errors are encountered.
