Software Engineering Struct pointer in C In this article, we will learn about the structure pointers , in C/C++ we have a feature to use pointers with Structure. Like pointers to other data types we can use pointer to structure.
Software Engineering Typedef function pointer in C The keyword typedef is used to define new data type names in C/C++. Here we should not not mistaken that we are creating any new data type, we should carefully note that we are just giving new names to the data types already available to us by C.
Software Engineering Header file math.h in C language math.h header file is a widely used C utility that we can use in C language to perform various mathematical operations like square root, trigonometric functions and a lot more. We have explored this in depth.
Software Engineering Trigonometric Functions using <math.h> in C math.h header defines various mathematical functions including trigonometric and hyperbolic functions. All the these predefined trigonometric functions use radians as argument. We have explored all Trigonometric Functions using in C.
Software Engineering Linear Search in C Programming Language We have explored Linear Search algorithm and implemented variants of Linear Search in C Programming Language. The variants we have explored are Linear Search in array in C, Linear Search in Linked List in C, Linear Search in array with duplicates and Linear Search in Linked List with duplicates.
Software Engineering Complete guide on stdlib.h in C is the header for the General Purpose Standard Library of C programming language which declares a variety of utility functions for type conversions, memory allocation, process control and other similar tasks.
Software Engineering Reverse a large file using IO Syscalls (using chunks) In this article, we have used different system calls (syscalls) in order to reverse a large file (>1GB) using a chunk size rather than character by character. We have demonstrated this with a C code.
Software Engineering Introduction to I/O System call, file descriptor and modes in C In this article, we shall learn the basics of I/O syscalls, file descriptors and modes in C. System calls include open. close. creat and more.
Software Engineering Complex number in C Programming language In this article, we will explore how to use complex numbers in C. There are two approaches: one is to implement it using struct in C and the other solution is to use complex.h library.
Software Engineering Delete an array in C In this article, we have explored how to delete or deallocate an array in C. By deleting an array, we mean to deallocate the memory that was assigned to the array so that it can be reused.
Software Engineering Traversing folders in C recursively In this article, we have explored how to traverse folders in C recursively. We have used the dirent.h library to achieve this along with basic methods like readdir, opendir and closedir.
Software Engineering Different ways to terminate a program in C In this article, we are going to learn about various methods by which we can terminate a C program which is currently in execution. Starting with the most widely used and most obvious function that is by using the exit() function.
Software Engineering Using complex.h header file in C In this article, we have explored the complex.h header file in C. The header file complex.h defines macros and functions to carry out operations on complex numbers in C.
Software Engineering Three dimensional (3D) array in C A 3D array is a multi-dimensional array (array of arrays). A 3D array is a collection of 2D arrays. We have explored 3D arrays in C in depth from defining such array along with basic operations.
Software Engineering Two dimensional (2D) array in C In this article, we have explored 2D arrays in C including declaring 2D array, calculating size, inserting elements and updating 2D array, convert 3D array to 2D array and using malloc to define 2D arrays in C.
Software Engineering Put array in register in C/ C++ Placing an array in a register can improve performance significantly but only statically allocated array can be placed in a register explicitly as we cannot deal with memory location directly. We have explained this in detail.
Software Engineering Variadic function in C/ C++ Variadic functions in C and C++ are the functions that can take any number of arguments. This is a central part of utilities like printf. We have explained this in detail with examples.
Software Engineering Rounding Functions in C / C++ In this article, we have focused on different rounding functions in C and C++ such as floor, ceil, round, trunc and fmod. We have explained each in detail with C++ code examples.
Software Engineering Variables in C Variable in C is a name of a memory location which holds a particular data as defined in the program. We have covered all points related to variables and the different types of variables as well.
Software Engineering Hyperbolic functions in math.h (C/C++) In this article, we have explored all hyperbolic functions in math.h library of C and C++ with code examples. It includes functions like Complex Hyperbolic Cosine (cosh), Inverse Hyperbolic Cosine (acosh), Complex Inverse Hyperbolic Cosine (cacosh) and other variants for sin and tangent.
Software Engineering chdir(), fchdir() and getcwd() in C chdir() and fchdir() are functions in C listed in unistd.h header file which is used to change the current working directory through code. This can be verified by getcwd() function.
Software Engineering Understand Pointers in C in depth In C, pointer refers to a specific memory location and gives the programmer finer control. There are several types of pointers like dangling pointer. We have explored everything in depth.
Software Engineering Understand use of Pointers (*) in C and C++ A pointer in C and C++ is a variable that contains a memory address which is usually the address/ location of another variable in the memory.
Software Engineering Ternary Operator in C Ternary operator in C is an alternative syntax for if else conditional statement. It is usually used to condense if else statements.
Software Engineering Get length of array in C and C++ In C and C++, we find the length of an array we need to use the sizeof operator and get the length as size of entire array divided by size of an element.
