The cin function in C is equivalent to the scanf function in C language, which is used to read 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.
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 :
int num;
cin >> num;
C:
int num;
scanf("%d", &num);
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.
