My C$++$ code is not printing the 'Night call is free' value where applicable in the Minutes used so far column, it isn't printing the correct values for the Cost column, and the Total cost of the bill is only displaying the basic monthly rate of $$39\mathrm{.}99.$ The code is below and a screenshot of the requirements is attached in the image.

Problem:

the day or the night.

daytime call.

information about each call on a separate line.

This information is:

The time of day that the call started $($using an int to represent a $24$ hour clock$).$

The duration of the call in minutes $($int$),$ and

A char for the type of call $-$ A for a call within the area, $L$ for a long$-$distance call.

For example, the line

$1830,20$ A

means that the call started at $6$:$30pm,$ lasted for $20$ minutes and was within the calling area.

SUGGESTION

You should design, compile, run and debug your program in stages.

You might start by testing if your program can just read and echo the data file.

After this is working accurately, write the code to determine whether the call is a day or night one.

Make sure you always submit$($upload$)$ the $.$cpp file$($s$)$ and the output file$($s$)$ or a screen shot of the output.

Sample output from the first few lines of the data follows:

Cellphone charges $-$ MP$3$ by $($your name goes here$)$

cout $$ setw$(5)$ "Time" $$ setw$(10)$ "Duration" $$ setw$(15)$ "Type of call" $$ setw$(20)$ "Minutes used so far" $$ setw$(10)$ "Cost" $$ endl;
