### Decision statments

call charging program using logical, arithmetic operators and decision statements if, if else, nested if, nested if else,:
if
call start from 8:00am - 19:59pm
call charges = 5rs

if
call start from 20:00pm - 07:59am
call charges = 3rs

what will be the call charges if call start from 19:45 and end at 20:15
???????

You need to write code, not us.
 ``1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162`` ``````#include main() { int startingHour, startingMint, callDuration,totalCharges, totalMint; cout<< "enter Starting hour "; cin>> startingHour; cout<<"\n"; cout<< " enter starting minute "; cin>> startingMint; cout<<"\n"; cout<< " enter call duration "; cin>> callDuration; cout<<"\n"; if( startingHour >= 8 && startingHour <=19) { totalMint = startingMint + callDuration; if ( totalMint>= 60) { startingHour + 1; } if( startingHour >= 20) { totalCharges = (59 - startingMint)*5 +(totalMint - 59)*3; } else { totalCharges = callDuration * 5; } } else { if( startingHour >= 20 && startingHour <=7) { totalMint = startingMint + callDuration; if ( totalMint>= 60) { startingHour + 1; } if( startingHour >= 20) { totalCharges = (59 - startingMint)*3 +(totalMint - 59)*5; } else { totalCharges = callDuration * 3; } } } cout<< " total charges = " <

this is the code but the else portion is not working it showing output 0
 ``` enter starting hour = 1 enter starting minute = 4 enter call duration = 2 total charges = 0 ```

kindly highlight the ERROR
`if( startingHour >= 20 && startingHour <=7)`

Can you think of any value of startingHour which is bigger than 20 AND less than 7? I can't.

Which bit of code do you think is supposed to be run when you enter 1 as the starting hour? You have not written any code for that.

 ``12`` ``````#include main()``````
This has not been C++ since before 1998. You should get a new, correct C++ compiler for free instead of whatever 20 year old mess you're using.

`if( startingHour >= 20 && startingHour <=7)`

i am using the 24 hour format and condition is

if
call start from 20:00pm - 07:59am
call charges = 3rs

and i found 1 mistake after correcting it still not working

 ``1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162`` ``````#include main() { int startingHour, startingMint, callDuration,totalCharges, totalMint; cout<< "enter Starting hour "; cin>> startingHour; cout<<"\n"; cout<< " enter starting minute "; cin>> startingMint; cout<<"\n"; cout<< " enter call duration "; cin>> callDuration; cout<<"\n"; if( startingHour >= 8 && startingHour <=19) { totalMint = startingMint + callDuration; if ( totalMint>= 60) { startingHour + 1; } if( startingHour >= 20) { totalCharges = (59 - startingMint)*5 +(totalMint - 59)*3; } else { totalCharges = callDuration * 5; } } else { if( startingHour >= 20 && startingHour <=7) { totalMint = startingMint + callDuration; if ( totalMint>= 60) { startingHour + 1; } if( startingHour >= 21) { totalCharges = (59 - startingMint)*3 +(totalMint - 59)*5; } else { totalCharges = callDuration * 3; } } } cout<< " total charges = " <
 if( startingHour >= 20 && startingHour <=7)

24 hour clocks have nothing to do with this.

Tell me a value for startingHour that you think will make this if block run, and I'll explain why it's wrong. This if block will never run. Never ever ever.
suppose startingHour =1
which compiler i should use. my instructor is gave me this. i am using bloodshed DEV-C++
 suppose startingHour =1

Okay. So, is this true?
`startingHour >= 20` No, startingHour is NOT 20 or more.

Is this true?
`startingHour <=7` Yes, startingHour is 7 or less.

So are they BOTH true? No.
So is this true?
`startingHour >= 20 && startingHour <=7` No, because this will only be true when they are BOTH true.

Pick another number that you think will make `startingHour >= 20 && startingHour <=7` true and I will explain why it does not.

Moschops i got it. can i use OR operator instead of AND??????
Can you?????? We're not here to do your homework for you.

`if( startingHour <= 20 && startingHour >=7)` i think this is the true statment. but its also not working

m not saying to do my home work i am asking for suggestion. well thanks dude :-)
if :

if( startingHour >= 8 && startingHour <=19)

give you one charge, what descision has been made about the other charge?

(hint : i'll charge you this, else i'll charge you that)
Moooce

other charges are applying in
 ``1234567891011121314151617`` ``````if( startingHour >= 8 && startingHour <=19) { totalMint = startingMint + callDuration; if ( totalMint>= 60) { startingHour + 1; } if( startingHour >= 20) { totalCharges = (59 - startingMint)*5 +(totalMint - 59)*3; } else { totalCharges = callDuration * 5; } }``````

but the code for these charges is not working
f
call start from 20:00pm - 07:59am
call charges = 3rs

 ``1234567891011121314151617181920212223`` ``````else { if( startingHour >= 20 || startingHour <=7) { totalMint = startingMint + callDuration; if ( totalMint>= 60) { startingHour + 1; } if( startingHour >= 8) { totalCharges = (59 - startingMint)*3 +(totalMint - 59)*5; } else { totalCharges = callDuration * 3; } } }``````

i am unable to find what will be the right statment in `if( startingHour >= 20 || startingHour <=7)`
