If two 8-bit numbers are added together it is quite possible that the sum will exceed 255, so how do we cope with larger numbers? In addition to other uses, int type variables are commonly employed to control the loops and to index arrays. Working with 31 bits that could represent the value of the number, the biggest positive binary integer we could have would be 31 ones after the first, sign bit of zero, which gives us a positive sign. Negative value: - 2 ^ (n-1) (where ^ stands for raised to power) INT_MAX UINT_MAX. (Depending on your system, this data type might be 64-bit, in which case its range is identical to that of the long long int data type.) Holds signed 32-bit (4-byte) integers that range in value from -2,147,483,648 through 2,147,483,647. So it has a finite minimum and maximum range. Products.
