C

There is a lot more to structures and unions. I’ll go through what I’ve learned about them here. I’m assuming that you’re not a beginner in C language. To store or manipulate data in the computer’s memory we need to write a computer program that’ll instruct the compiler or the interpreter to allocate space for the data in the memory. We give a name to that location in the memory to make retrieval and usage of data easy. That’s what we call a variable. Variable is the named location in the memory where we have stored some data. The data can be an integer number, floating-point number, character, or boolean. Data types classify what type of data the programmer intends to use.
