3.1.1 Rectangular or Polar Conversion Write a function in C with comment blocks that can optionally convert between rectangular polar coordinates. The values of the addresses passed into the functions are updated after the function call. Heres the prototype: void rectPolarConv(double * x, double * y, double * mag, double * ang, char convType); If convType = 0 then rectangular to polar conversion is performed. If convType = 1 then polar to rectangular conversion is performed. Write the code in main that can ask for coordinate data and the conversion type and display the result.
