Can scanf be used in c++?

Yes, the scanf function can be used in C language. The scanf function is used to read formatted data from the standard input stream (usually the keyboard). The specific usage is: int scanf(const char *format, ...); where format is a string specifying the format of the data to be read, ... is an address list of variables to store the data to be read. However, it is recommended to use alternative functions from the iostream library, such as cin, to avoid scanf's shortcomings such as security issues and formatting errors.
