Please create a basic function in C++ to compute the area of a triangle using only the corner points.

Given the corner points of a triangle (x1,y1),(x2,y2),(x3,y3), write a function to compute the area. Hint: The area of the triangle with corner points (0,0),(x1,y1), and (x2,y2) is 2x1y2x2y1 To use this formula, you shift the given triangle so that one of its corners falls on the origin. This shift does not change the area. The corner points of the triangle shifted by (x,y) are (x1x,y1y),(x2x,y2y),(x3x,y3y)
