Hi can someone help me with this C++ program, I'm using Xcode to do it.

Metals expand when heated and contract when cooled. For a typical aluminum bar, if you know the width at 70 degrees F, the new width at a temperature can be calculated with the following formula: new width width(at 70 degrees F) +(temperature -70)* 10 Write a function named widthAtTemperature, that takes two parameters: 1. a double value that represents the width of a bar at 70 degrees F 2. a double value that represents a temperature widthAtTemperature should return a double value that represents the width at the given temperature A researcher is performing an experiment, and the size of the bar can only vary within a given tolerance. Your goal is to output a chart showing the width of a bar at a series of temperatures and indicating which widths are within the tolerance range. For example the following shows the output for a bar of width 10.0 cm at 70 degrees F and a tolerance of 0.00050. The symbol is used to mark the usable temperature range. Inter the har udth at 'H d': grees F: -1 Enter the tolerance For vidth variationH Tenperature (degrees F> idth .9991 61 62 63 64 65 606 60 69 1H.HMM1 1H.HHM4Mx 1M.MMG 29 1M.MM1MM Your main function should do the following: Input values for the width at 70 degrees F and the width tolerance
