C$.$ Program $-(10$pt$)$

Write a program that you enter the start time of a phone call using a floating point value such that $7$:$15$ am would be $7\mathrm{.}15$ and $7$:$15$ pm would be $19\mathrm{.}15$

Also the number of minutes the call lasted $($do not allow negative values$)$ presume whole minutes are used

There are three rates charged

Before $7$:$00$am $$0\mathrm{.}15$ per minute

Between $7$:$00$ am and $7$:$00$ pm $$0\mathrm{.}25$ per minute

After $7$:$00$pm until midnight $$0\mathrm{.}20$ per minute

The charges are only based on the start time not how long or when it ends

From the example note that valid minutes and start times must be entered

Example Output

Phone Charges Calculator

Using a floating point such that $4$:$45pm$ would be entered as $16\mathrm{.}45$

What time did the phone call start? $25\mathrm{.}15$

That is not a valid time please re$-$enter

What time did the phone call start? $15\mathrm{.}75$

That is not a valid time please re$-$enter

What time did the phone call start? $6\mathrm{.}55$

How many total minutes did the call last? $-3$

Invalid number of minutes

How many total minutes did the call last? $14$

The phone call started at $6$:$55$ and was $14$ minutes

using a rate of $$0\mathrm{.}15$ per minute cost was $$2\mathrm{.}10$ in c$++$
