cin.clear();
In C++ we clear an input buffer as follows: std::cin.clear(); // clear the error state (if any) std::cin.ignore (numeric_limits<streamsize>::max()); // read and ignore everything until EOF
scanf();
For basic input and output in C++: #include
Input a variable.
Use the C++ getline() function from the standard library.
The C and C++ library routines for output might, or might not, include use of different buffers. If they are the same buffer (unlikely) then you can simply intermix the techniques. If they are not the same buffer then you need to do a flush sequence between techniques.
input is the << operator and output is the >> operator
clear() is an inbuilt function defined in c++ defined in conio.h. It is used for clearing the console. The systax is:clear();
The scanf function in C can read a maximum of characters determined by the format specifier used and the size of the input buffer provided. For example, if you use %s, you should specify a maximum field width to prevent buffer overflow (e.g., %10s reads up to 9 characters plus the null terminator). Without a specified width, scanf will read until it encounters whitespace, but this can lead to undefined behavior if input exceeds the buffer size. Always ensure to use proper buffer sizes and field widths for safety.
Use an SLR parser algorithm.
No. In C++ with <iostream>, cin is a prefedined class that represents stdin, so it is an input identifier.
I guess you mean either input/output/inout/append or binary/text.
