Write a program that, after pressing the F1 key, prints the operating instructions, F2 starts the measurement and the program ends F10 or ESC. The measurement will consist in the fact that the program generates a random character (letters are enough), displays it in the middle of the window and starts the time measurement. The measurement stops when the user presses the same key. If the user presses something else, the program will ignore it. Finally, the program prints the measured time that elapses from the printout to the pressing of the same key. Example:

      Press: X       …. 1.25 s         compressed X

               Press: Z       … .. 33.12 s     pressed successively   ABCDEF… Z

               End      pressed      F10

Tip: Instead of the conio.h library, you can use others, such as curses.h or ncurses, used in the Unix world.

write the program in c language.
