write three c$++$ functions:

One function to collect and return a number between $1$ and $100,$ inclusive. If the user enters a number that is not between $1$ and $100,$ the program will ask the user to a new number. The function only returns a number $($integer$)$ between $1$ and $100.$ This number will be used as time.

One function that will calculate the falling distance of an object using the following formula:

Distance $=0\mathrm{.}5*$gravity$*$time$*$time;

The function returns the calculated distance as a float value.

The gravity is set as a global variable with value of $9\mathrm{.}8.$

The time is collected from the first function and passes as a parameter.

One function to prompt the result as

The falling distance is $\_\_\_\_\_$ meters
