(C++) int

Data type (and thus a keyword) that can hold a single whole number.

The range of an int can be found at compile time with std::numeric_limits.

If you assign a broken number to an int, this value gets rounded down. Your compiler should give you a warning then, as in the example below.

include <cassert>


int main()
{
  const int myValue = 12;
  const int myBrokenValue = 12.9;
  assert(myValue==myBrokenValue);
}

Prefer a plain int over a short int or a long int (ref. 1, 4.10.14)
