main


              12345678910
            
#include <iostream>

int main()
{
	long int large_number = 4000000000;
  	short int small_number = 45;
  	
	std::cout << "Large number: " << large_number << std::endl;
	std::cout << "Small number: " << small_number <<std:: endl;  
}

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:

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.
