classes / pow function

[jbutcher]

Im working on a simple class program which creates coordinate points and calculates the distance between the points. i keep getting an error when i try to calculate the distance.

thanks for the help

// the code
half1 = pow((EndPoint.GetXCoordinate()-Startpoint.GetXCoordinate(),2));
half2 = pow((EndPoint.GetYCoordinate()-Startpoint.GetYCoordinate(),2));

Length = sqrt[half1 + half2];

//and the error messages
/usr/include/bits/mathcalls.h: In function ‘void CalcDistance(Point, Point, Point)’:
/usr/include/bits/mathcalls.h:154: error: too few arguments to function ‘double pow(double, double)’

You have extra parentheses in the pow calls and you are using square instead of round brackets when calling sqrt
