As part of this series of articles, we are discussing buffered and un-buffered functions dealing with file management. We already discussed buffered functions in our previous articles and started discussing un-buffered functions. We have seen open and close functions in the previous article. In this article, we will discuss a few more un-buffered file management […]
Structures in C are used to group multiple variables of the same or different types. The variables inside the structures can be accessed through its structure variables. I recommend you to read the article, “C Programming – Understanding Structures in C“, before proceeding with this. Usually, ‘C’ structures are to group related information. ‘C’ compiler […]
We have discussed that ‘C’ provides buffered and un-buffered functions for file management. We have already discussed some of the buffered functions in our previous articles; “C Programming – Dealing with files – How to read from a file?“, “C Programming – Dealing with files – How to write to the file?” and “C Programming – Dealing […]
In our previous article, we have used “getrecord” function. We will start this article with this function. We have to implement “getrecord” to fetch a record from the “employee.dat” file. It will check the “employee.dat” file for an employee record based on the given employee number. If it finds the employee record it will return […]
We have discussed opening & reading from the file in our previous Article “C Programming – Dealing with files – How to read from a file?“. fwrite function Another important buffered function, ‘C’ provides is fwrite function. fwrite function writes to the file. The file should be opened with fopen function call. The syntax of […]
C library provides a good number of file handling functions to deal with files and directories/folders. Generally, we can classify these functions as: Buffered functions and Un-buffered functions. Un-buffered functions are the raw functions that deal directly with storage devices. Whereas, buffered functions maintain memory buffers to improve the performance and reduce the number of […]
“printf” is a very famous function in “C” Programming. This is the primary function we use in “C” to display something on the screen. If you are a serious developer, definitely you will get a thought on developing the “printf” function or you will get a question “How it was developed?”. “printf” is a special function. […]
One of the beautiful features of ‘C++’ is its ability to support Operator Overloading. ‘C++’ Operator Overloading allows changing the behavior of operators when using them with ‘C++’ class objects. One of the best examples of Operator Overloading is the ‘+’ operator. Usually, the ‘+’ operator will add two integer operands and produce an integer […]
C language Programming provides functions to create and release memory dynamically. There are two types of functions ‘C’ provides: One type of functions allocates memory in the heap. malloc calloc realloc Other type of function(s) release the memory from the heap. free Now you will get the doubt; why release memory functions are required? Why […]
In ‘C’ programming we can pass arguments to an application or a program. We can call this as passing command-line arguments. I know you will ask the question “How to pass them?”. Good. Fortunately it is simple. As you aware, main() is the function where the execution of the program starts in ‘C’ programming. That means, if […]
