Question 1.Assign1 semester2

Hi All!

I am not quite sure which iteration loop to use between while loop or do while loop. But i found if statement perfect for this question, check the code below:


if (ans=='y' || ans=='Y'
{
cout<<"How many modules repeating?"<<endl;
cin>>no_repeat;
total = calcFee(no_module, fees, no_repeat, repeat_fees);
}
else
{
total= calcFee(no_module, fees);
}
Anyone with different opinion please advise...

If you want your loop to happen 0 or more times -> while loop

If you want your loop to happen 1 or more times -> do ... while loop

Hi there,

My suggestion to you is for you not to use the ELSE statement, the program must call the "New module" function no matter if the student is repeating moules or not.

Good luck!

Hi Everyone.

I have a bit of a problem with validating my input and would really appreciate your help. I will post the code and then explain the problem.

Language: C++
if ((repeat == ';Y';)or(repeat == ';y';))
    {
 
        cout<<"\nHow many modules will the student repeat? : ";
        cin>>repEnrolled;
 
        cout<<"\nHow many new modules will the student take? : ";
        cin>>newEnrolled;
 
        totalTuition=calcFees(newEnrolled, NEW_FEE, repEnrolled, REPEAT_FEE);
 
    }//if loop
    else
    {
 
        cout<<"\nHow many new modules will the student take? : ";
        cin>>newEnrolled;
 
        totalTuition=calcFees(newEnrolled, NEW_FEE);
 
    }//else loop

Ok, now basically, everything works fine when I use valid input, but when I use invalid input e.g. a character or floating point value instead of an integer, the program goes a bit crazy. How can I validate the input as integer values?
Having looked on the web, there were solutions like using cin.good() in a while loop which resulted in an infinite loop.
Let me know what you guys think.

Thanks
