long vs int java
An int is a 32-bit integer; a long is a 64-bit integer. Which one to use depends on how large the numbers are that you expect to work with.
int and long are primitive types, while Integer and Long are objects.
Primitive types are more efficient, but sometimes you need to use objects;
for example, Java's collection classes can only work with objects,
so if you need a list of integers you have to make it a List<Integer>, for example (you can't use int in a List directly).what is a long long int in c

int main(void) {
/*
A long int is:
32-bit compiler:
MIN: -2,147,483,648
MAX: 2,147,483,647
unsigned MAX: 4,294,967,295
64-bit compiler:
MIN: -9,223,372,036,854,775,808
MAX: 9,223,372,036,854,775,807
unsigned MAX: 18,446,744,073,709,551,615
Therefore...a long int will either be
-2,147,483,648 and 2,147,483,647 for a 32-bit compiler
or -9,223,372,036,854,775,808 and
9,223,372,036,854,775,807 for a 64-bit compiler,
whilst a long long int will just be
-9,223,372,036,854,775,808 and
9,223,372,036,854,775,807
I hope this made sense!
