Help needed in c program ! Thanx :)

For the following problems use the following equations that give relationship[s between temps in Fahrenheit(F), Celsius (C), Kelvin (K) and Rank (R): F = R-459.67 F = (9/57C +32 R = (95)*K 1. Write a program to generate a table of conversions from Fahrenheit to Celsius for values from 0 degrees Fahrenheit to 100 degrees Fahrenheit. Increment by 5 degrees. Bring these values in from files called far.txt and cel.txt. Output your answers to answer.txt 2. Write a program to generate a table of conversions from Celsius to Rank. Use the cel.txt file as your starting Celsius values. Print your conversions to the command window
