<center>`short` and `long` are the type modifiers.</center>

main.cpp

What those type modifiers do is change the size of a type. While int takes up 4 bytes, short int takes up 2 bytes, and the long int 8 bytes of memory.

Note

There is a shorter syntax available you can use any of them:

  • short is equivalent to short int;
  • long is equivalent to long int;

So, we need to use long (long int) to store large values.
In contrast, we can use short (short int) to take up less memory. However, its range is narrower because of that. Here is the table with ranges that a type can hold:

Type Size (bytes) Range
short int 2 -32,768 to 32,767
int 4 -2,147,483,648 to 2,147,483,647
long int 8 -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807

Note

On Windows, long also takes up 4 bytes, just like int.

If you are working on Windows, you should use long long int (or long long) instead of just long.

Завдання

  • Change the type of the variables so it can hold a larger number.
  • Output the result of the expression.
