Hi i have created a program for my college assignment which asks to create a program for a telephone company that requires the program to calculate call charges for their customers, and also give discount calls depending on the time of day and day of the week.

The assignment also asks for the program to loop to give the user the option of entering data for second or third call.

So far i have done 95% of the assignment

My program asks the user to

1 input the day which call was made
2 input start time of call
3 input end time of call

Then my program outputs the

1 Number of calls made
2 Day on which the call was made
3 Call start time
4 Call end time
5 Total duration of call in minutes
6 Total discounts if any
7 Total less discounts, if any

Then my program asks the user do they want to make another call, if the user chooses yes, the program loops back to the beginning.

BUT!! This is the bit i need some advice and help,

The last part of my assignment asks me to output the totals for all calls that the user has entered into the program, any advice and help is very much welcome


below is my code

//This program will output a statement

Without looking at your code, i would just have an int that i would add at the beginning of the while loop. something like this

int i = 1;

do
{
   //functions
}
while()
{
   i++;
}
