Consider a text editor that saves a file whenever you click a save button. Suppose that when you press the button, the editor simply (1) animates the button "down" event (e. g., by coloring the button grey), (2) uses the write() system call to write your text to your file, and then (3) animates the button "up" event (e. g., by coloring the button white). What bad thing could happen if a user edits a file, saves it, and then turns off her machine by flipping the power switch (rather than shutting the machine down cleanly)

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)
