Please give a C program code that works.

Please help me write a C program that will perform the False Position Method that will solve the equation f(x) = -13 -20% +19x-32. The program should allow the user to input the upper and lower bounds arbitrarily but it also has to ensure a root that exists between the interval. There should be an error criterion of 0.1%. Results should also be shown of all iterations in tabular form on the screen or a text file
