In short, regular expressions, or Regex, are widely used in the UNIX world. Import the re Module The re-module in Python gives full supportContinue Reading
Introduction to the Python regular expressions Regular expressions (called regex or regexp) specify search patterns. Typical examples of regular expressions are the patterns for matching email addresses, phone numbers, and credit card numbers. Regular expressions are essentially a specialized programming language embedded in Python. And you can interact with regularContinue Reading
Function Pointer in C Language The pointer variable which holds the address of a function is called a function pointer. The basic advantage of a function pointer is that 1 function can be passed as a parameter to another function. Function pointer calls are faster than normal functions. We alreadyContinue Reading
Dangling Pointer in C Language: The most common bugs related to pointers and memory management in C Programming Language is Dangling/Wild Pointers. Sometimes as a programmer, we forgot to initialize the pointer with a valid address, and when we do so, then this type of uninitialized pointer is known asContinue Reading
Passing Structure as a Parameter to a Function using Call by Value in C Language: Let us understand how to pass a structure as a parameter to a function using the call by value mechanism in C Language. For a better understanding of this let us first create a structureContinue Reading
Passing Array as a Parameter to a Function in C Language: Let us understand this directly with an example. Please have a look at the following example. As you can see in the below code, the main function is having an array of size 5 and it is also initializedContinue Reading
Let us understand How to Access a Structure using a Pointer in C Language with an example First, we will see how to access the structure using normal variables, and then we will see how to access the structure using pointer variables. Please have a look at the following code example.Continue Reading
Error Handling in C Program: There is no direct support for Error Handling in C language. However, using the return statement in a function, there are few methods and variables defined in error.h header file that can be used to point out the error.
