Data Types in C Programming Language

The types of data stuctures provided by C can be classified under the categories:

1) Fundamental data types
2) Derived data types

Fundamental data Types in C Programming Language

Fundamental data types include the data types at the lowest level, i.e. those which are used for actual data representation in the memory. More about Fundamental data Types in C

Derived data types in C Programming Language

Derived data types are based on fundamental data types, i.e. a derived data type is represented in the memory as a fundamental data type. More about Derived data types in C

The standard input-output functions are buffered, i.e, each device has an associated buffer through which any input or output operation takes place. After an input operation from the standard input device, care must be taken to clear the standard input buffer lest the previous contents of the buffer interfere with subsequent input operations. The output buffer is cleared only if a newline character is used, or if an input function is used or the buffer is explicitly cleared.
