max value of double c++

The maximum value of a double in C++ can be obtained using the limits header file. The max value can be obtained by accessing the constant DBL_MAX which represents the maximum finite value of type double. Here is an example of how to obtain the maximum value of a double in C++:

#include <iostream>
#include <limits>

int main() {
    std::cout << "Maximum value of double: " << std::numeric_limits<double>::max() << std::endl;
    return 0;
}
