Data types are really important in programming. They show what kind of information a variable can hold. Here are some key data types and what they do:
Integers: These are whole numbers. Examples include 5 or -10. They usually take up 4 bytes of memory.
Strings: These are groups of characters. For example, the word “Hello” is a string. Each character in a string uses 1 byte.
Booleans: These show true or false values. They only take up 1 byte.
When programmers understand these types, it helps them use memory correctly. It also helps to avoid mistakes, since different types have different rules. For example, if you try to multiply a string, it will cause an error when the program runs.
