While Loop in C++ Programming Language

Image
  While Loop in C++ Programming Language We have discussed about the entry-controlled loop or pre-tested loop previously in our blog posts. These statements or loops are used to repeat a piece of code for a specific number of times as per our program requirement. We have studied about the for loop already. Today in this blog post we are going to study about the while loop in C++ programming language. And we will look at how this while loop actually works and how we can stop it by making some condition false so that the loop might not run infinitely. We use while loop in C++ program when the number of iterations is not known in advance and depends on the condition. When we know exactly that how many times a loop should run then we use the for loop instead of while loop.

What is File Handling in the C Programming Language

  What is File Handling in the C Programming Language In programming languages, we sometimes encounter situations where we need to store data from a program. Sometimes, it is not enough to just create data during program execution and lose it as the program stops. So, in such situations, we need to store data at some permanent location so that we can access it later on and perform certain operations on it. These operations include creating a new file, opening a file, reading from a file, writing to a file, and deleting the file. From here the concept of file handling comes into the picture. This file handling helps us to store the data permanently and then perform various operations on that stored data and use that data for other important purposes. So in simple words, a file is a location or container in computer storage devices for storing the data.
