and (c) int getXSamples(float xl. float in float max loat step)which computes returns samples of the x-axis from xmin to xmax with a step size of step. The function also returms the number of samples created (d) Write a main to generate samples of the r-axis from -1 to 1 with a step of 0.25 and then map these real x-values to pixel values between 50 and 550 and produce an output as shown below : -1.00 -0.75 -0.50 -0.25 0.00 0.25 0.50 0.75 1.0 xPix: 50.00 112.50 175.00 237.50 300.00 362.50 425.00 487.50 550.00
