How recursive bubble sort work

                                              Recursive Bubble Sort Base Case: If array size is 1, return. Do One Pass of normal Bubble Sort. This pass fixes last element of current subarray. Recur for all elements except last of current subarray. Example: Index=     0 1  2 3 4 5 6 7   100                          90 80 70 60 50 40 30  Array []= Suppose we want to sort the above in the increasing order by the recursive bubble sort. Make a get grater which will return the grater of the array. Compare the first and last element of the array if the first is greater than last the swap with each other. And again call the sort function and decrement the array size by 1; 1) 30                     90 80 70 60 50 40 100    ...

ARITHMETIC OPERATORS IN C


Arithmetic operators are commonly used in a variety of programming languages. In C, there are five of them and they all take two OPERANDS – an expression that is required for an operator to work. For example, for 2 + 3, 2 and 3 are considered as operands. The following table shows Arithmetic Operators:
Operator Name
Symbol
Multiplication
    *
Division
    /
Addition
    +
Subtraction
    -
Modulus
    %

In addition to division operator, C also provides modulus operator (%) which returns remainder on dividing one integer with another. Thus the expression 10/2 yields 5, whereas 10%2 yields 0. Modulus operator cannot be applied on float. Also using %, sign of remainder is always the same as sign of numerator. Thus -5 % 2 yields -1, whereas 5 % -2 yields 1.

Arrays in C Programming Language

Image
Array is a data structure in C++, which stores a fixed size sequential collection of elements of the same type. An array is used to store a collection of data. It is often useful to think of an array as a collection of variables of the same type. Instead of declaring individual variables, such as number0, number1, ..., and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and ..., numbers[99] to represent individual variables. A specific element in an array is accessed by an index. All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element. Declaring an array in C, the programmer specifies the type of the elements and the number of elements required by an array as follows:   type array-Name [ array-Size ]; This is called a single-dimension array. The array-Size must be an integer constant greater than zero and type can be any valid C data type...

Pointers in C

Image
Pointer is a variable that points to or references a memory location in which data is stored. This means that a pointer holds the memory address of another variable. Put another way, the pointer does not hold a value in the traditional sense; instead, it holds the address of another variable. A pointer "points to" that other variable by holding a copy of its address. Because a pointer holds an address rather than a value, it has two parts. The pointer itself holds the address and that address points to a value. Pointer declaration is shown below. You start by specifying the type of data stored in the location identified by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Finally you give the name of the variable. Data-type *variable-name Such a variable is called a pointer variable. When we define a pointer variable we do so by preceding its name with an asterisk. In C, we also give our pointer a type which, in this case, refe...
