Input

Input in C++ is the process of reading data from an external source, such as a keyboard, mouse, or file. It is an important part of C++ programming because it allows the program to respond to user input and take action based on that input.

Types of Input

In C++, there are several different types of input available.

Keyboard Input

The most common type of input is keyboard input. This type of input uses the standard input stream (stdin) to get data from the user. To get keyboard input in C++, the cin object is used.

Mouse Input

Another type of input is mouse input. This type of input allows the program to detect mouse events, such as clicks, movements, and scrolling. To get mouse input in C++, the SDL library can be used.

File Input

C++ also supports file input. This type of input allows the program to read from a file and process the data within the file. To get file input in C++, the fstream library can be used.

Process Input

Once the data has been obtained from the input source, the program must process the data to make it useful. In C++, this is done using functions and data structures. For example, if the program needs to store data from a file, it can use a vector or array to store the data.

Conclusion

Input is an important part of C++ programming. By using the different types of input available, such as keyboard, mouse, and file, the program can respond to user input and take action based on that input. By using functions and data structures, the program can then process the input and make it useful.
