Calloc Function ( Dynamic Memory Allocation Part -3 )

-

Definition

Calloc function allocates  series of similar bock of elements in the heap which is executed and allotted at the runtime of the program execution. As the program instructions cannot directly access heap memory, so a pointer is required which points to the memory address of the first memory byte allocated by the calloc function in heap. 

The calloc returns a void pointer which is to be type-casted to the convenient data type as in use by the user. 

Malloc function is declared under stdlib.h library. So include this in the program in the section of the header files, to avoid getting a warning or syntax error in certain compilers.

The general syntax of the calloc function is :


< data_type> *pointer; 

pointer  = ( < type casting * > ) calloc(< number of elements >,< byte_size >)
 For storing float in the dynamic memory we can use :

float *pointer;





pointer= ( float* )calloc(5,sizeof( float ))

A program using calloc function :


A similar method of doing the same problem

Bubble Sort ( C & Python 3)

Bubble Sort Algorithm Bubble Sort   is a simple algorithm which is used to sort a given set of  n   elements provided in form of an array with  n  number of elements. Bubble Sort compares all the element one by one and sort them based on their values. If the given array has to be sorted in ascending order, then bubble sort will start by comparing the first element of the array with the second element, if the first element is greater than the second element, it will  swap   both the elements, and then move on to compare the second and the third element, and so on. If we have tota l   n   elements, then we need to repeat this process for  n-1  times. It is known as  bubble sort , because with every complete iteration the largest element in the given array, bubbles up towards the last place or the highest index, just like a water bubble rises up to the water surface. Sorting takes place by stepping through all the elements one-by-one and comparing it with the adjacent elemen

Comparison Logical and Bitwise Operator ( Java Part - 4 )

J ava Comparison Operators Comparison operators are used to compare two values: Operator Name Example Try it == Equal to x == y Try it » != Not equal x != y Try it » > Greater than x > y Try it » < Less than x < y Try it » >= Greater than or equal to x >= y Try it » <= Less than or equal to x <= y Try it » Java Logical Operators Logical operators are used to determine the logic between variables or values: Operator Name Description Example Try it &&  Logical and Returns true if both statements are true x < 5 &&  x < 10 Try it » ||  Logical or Returns true if one of the statements is true x < 5 || x < 4 Try it » ! Logical not Reverse the result, returns false if the result is true !(x < 5 && x < 10) Try it » Java Bitwise Operators Bitwise operators are used to perform binary logic with the bits of an integer or long integer. Operator Description Example Same as Result Decimal & AND -

Something about me  H ey peeps, its me Abhishek and it's my first blog ever . I wanted to write something about me, but you know there are people about whom you can write about a trillion lines about their deeds, achievements and there are some people like me, having no achievements and nothing to write about, a single line would be too long I guess lol. Jokes apart, through this blog I will convey and provide all the study materials, which I could gather in my B-tech college life.
