Day 3

 Hello my friends, today is my third day in How to Learn Java in 45 Days and today I took the following videos. I learned how to write code and the difference between strings, ints and
floats.

Strings are written text that is printed in the output as you wrote it and is between quotation marks.

As for ints, they are whole numbers that do not contain any fractions or decimal points.

As for floats, they are numbers that contain fractions.

 We must know the difference between them and know when to use each one in its place. If we make a mistake in any of them, the code will not work and there will be an error. Here I made this mistake and realized it when I reviewed the code well and corrected it and learned from it and wrote it in the notes so that I would remember it next time. Today I printed my first work, which is a primitive calculator where it takes the number I entered in the input and reads the entered sign such as + for example, and I enter the number I want to add to it, and then the computer processes it and prints the result in the output that appears to me. It was really fun and I was happy with the first line of code I wrote in my life and I am very excited for the next day. See you tomorrow
