2. The conversion formula for converting Celsius to Fahrenheit temperature is Fahrir (Celtis 2.5.bj + 32.0 The approximate conversion formula is given by Fahrenheit Celsius 3) + 30 (a) Starting from a Celsius temperature of 0 degrees, write a C++ program that determines when the approximate equivalent Faheenheit temperature differs from the exact cquivalent value by more than 4 degrees Use a while loop the terminates when the difference between approximate and exact sheenheit equivalents exceeds 4 degrees. How many times does the while loop executed? (b) Wnica C++ program that produces a table of Celsius temperatures, exact Fahrenheit equivalent temperatures, approximate Fahrenheit equivalent temperature, and the difference between the exact and approximate equivalent Fahrenheit values. The table should begin **0 degrees Celes, use 2-degree Celsius increments, and terminate when the difference between exact and approximate values is more than 4 degrees 3. The expansion of a steel bridge as it is heated to a final Celsius tenperature, T6, from an initial Celsius temperature, Ta can be approximated by using this formula is the coefficient of expansion which for Moel is 11.7x10 L is the length of the bridge at temperature Write a program that displays a tahle of expansion lengths for a steel bridge that is 7365 meters long at 0 degrees Celsius, as the temperature increases to 40 degrees in S-degree increments. Use for loop
