The scanf() function reads formatted input from stdin according to a format string and assigns the data to specified variable(s). The input data is a character sequence which is converted to the appropriate type, as per the format string, before being assigned to the corresponding variable.

Examples:

unsigned x;

scanf("%u", &x);

In the above example, we read an unsigned integer (%u) from the stdin character stream and assign the resultant value to the variable x.
