Answer to Question #50866 in C++ for chad

Question #50866
The fact that most metals expand when heated and contract when cooled has serious implications when the dimensions of a piece of laboratory equipment are critical to an experiment. A typical aluminum bar that is w cm wide at 70 degrees Fahrenheit will be

x =w + (t – 70) x 10-4

cm wide at a nearby temperature t. Write a program that prompts the user for the standard width of a bar at 70 degrees Fahrenheit and for a tolerance for width variation. Then display a table like the one below indicating the bar’s width at temperatures from 60 degrees to 85 degrees in one degree intervals and marking with a star (*) the temperatures at which the bar’s width is within the tolerance.



Sample Output:

Ideal Bar Width (at 70 degrees F): 10.00000 cm

Tolerance for Width Variation: 0.00050
