Question

How much long a variable can be?​

Answer 1

Answer:

Therefore, if a variable or constant may potentially store a number larger than

2,147,483,647 (231 : 2), it should be defined as a long instead of an int. NOTE: In standard C, a long integer may be limited to a 32-bit value ranging from -2,147,483,648 to

2,147,483,647.
