stdnumericlimitsintmax

std::numeric_limits<int>::max is a constant defined in the C++ Standard Library, specifically within the <limits> header. It represents the maximum finite value that an object of type int can hold. The value of std::numeric_limits<int>::max is determined by the implementation of the C++ compiler and the underlying hardware architecture. For most modern systems, this value is typically 2147483647, which is derived from the fact that a 32-bit signed integer can represent values from -2147483648 to 2147483647. This constant is useful in programming when you need to ensure that a variable does not exceed its maximum possible value, helping to prevent overflow errors. It is part of the std::numeric_limits template class, which provides a standardized way to query properties of arithmetic types.
