Stack. Because of its LIFO (Last In First Out) property it remembers its ‘caller’ so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls. Every recursive function has its equivalent iterative (non-recursive) function. Even… Continue reading
Two. One queue is used for actual storing of data and another for storing priorities.
The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a… Continue reading

A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data.
Say your program sometimes deals with English text (which fits comfortably into 8-bit chars with a bit to spare) and sometimes Japanese text (which needs 16 bits to cover all the possibilities). If you use the same code to manipulate either country’s text, will you need to set aside 16… Continue reading
Multibyte characters are another way to make internationalized programs easier to write. Specifically, they help support languages such as Chinese and Japanese that could never fit into eight-bit characters. If your programs will never need to deal with any language but English, you don’t need to know about multibyte characters…. Continue reading
The operations +, –, *, and / (addition, subtraction, multiplication, and division) are available for both integer and floating-point arithmetic. The operator % (remainder) is available for integers only. For floating-point math, many other functions are declared in the header file math.h. Most of these functions operate in double-precision floating… Continue reading
Identifier names beginning with two underscores or an underscore followed by a capital letter are reserved for use by the compiler or standard library functions wherever they appear. In addition, all identifier names beginning with an underscore followed by anything are reserved when they appear in file scope (when they… Continue reading
