http://www.sanfoundry.com/cpp-program-find-closest-pair-points-array/ I can run this without any errors in mingw c++ but with so many errors in visual c++ 2013. why?

  • Please describe which steps you took when you attempted to compile the code in Visual C++, and provide a sample of the errors reported. – Ole Wolf Nov 28 '17 at 07:26

First, they use two different C/C++ compiler - Microsoft C/C++ Compiler and GCC.

Your sample use Variable-length array like here.

float closestUtil(Point Px[], Point Py[], int n)
{
    ...
    int mid = n / 2;
    ...
    Point Pyl[mid + 1];
    Point Pyr[n - mid - 1];
    ...
}

Programming languages that support VLAs include Ada, Algol 68 (for non-flexible rows), APL, C99 (although subsequently relegated in C11 to a conditional feature which implementations are not required to support; on some platforms, could be implemented previously with alloca() or similar functions)

-- variable-length array on wikipedia.org

The Microsoft compiler do not support Variable-length array[1] (is not C99 compliant[2]) and GCC support it as and extension[7].

To solve this you can replace them with std::vector.

You can turn the GCC warnings as explained here.
