Typecasting

Typecasting is like assigning a label to things that look and act alike. Just like we call both big and small dogs, "dogs". We do this because dogs have specific qualities, like four legs, fur, and the ability to bark, that make them different from cats, which have tails, walk on four legs, and meow.

Similarly, in programming, typecasting is the process of assigning a data type label to a value, so that the computer understands what kind of data it's dealing with. This helps the computer sort and use data in the way it is supposed to.

For example, let's say you have two numbers: 1 and 2. By default, they are both integers. But you can typecast one of them as a float (a number with a decimal point), like this:

float num = (float) 2;

Now, num is a float, even though it originally was an integer. This means you can perform operations on it that were not possible before.

In simpler terms, typecasting labels data so that the computer can understand it better and do more things with it.
