    Need help student urgent

    Hello..!!

    For the past 2 weeks due to medical problems, i was unable to attend my courses at University. Yesterday,while checking my university mail, I saw that assignment. I've got this computer programming work to be submitted online today at latest midnight, i.e, 7 hours left, to complete this work.

    Given I was absent in class, I completely lost for the two last question. When I saw them, I was like "WTF! Did we do that in class!!". I'm still a first year student. So, i'm still a beginner in program design. I'm used to using the <stdio.h> library. I'm usin Dev C++.

    If possible please explain the logic behind the codes used.

    Please Help..!!

    I'd be really grateful.

    Here they are:

    According to University regulations, the following mapping between a students final mark and the indicative classification of degree is provided for guidance of the board of examiners.

    >= 70 First Class Honours
    60-69 Upper Second Class Honours
    50-59 Lower Second Class Honours
    40-49 Third Class Honours
    <40 Not an honours degree

    (There are other regulations that affect the degree classification.)

    Write a program to prompt the user to enter a mark as a floating point number. Check that the mark is in the range 0.0 100.0 and, if it is, display the indicative degree classification according to the mapping above and if not, then display a message saying that the marks input is invalid.

    Test your program to ensure that the mapping is correct.


    Next one:

    The UK sequence of traffic lights is:
    "Red" (means stop); this is followed by:
    "Red and Amber" (means prepare to go); this is followed by:
    "Green" (means go); this is followed by:
    "Amber" (means prepare to stop); this is followed by:
    "Red"; etc..
    Write a program that prompts the user to enter the current state of a traffic light, then displays the next state.

    For example, if the current state is "Red and Amber", the next state is "Green".

    Use a menu system to obtain the current.



    Thank You..!!

    For question 4,

    #include<iostream.h>

    void main()

    {

    float num;

    cout<<"Enter marks:"<<endl;

    cin>>num;

    if(num>=0.0 && num<=100.0)

    {

    if(num>=70.0)

    cout<<"First Class Honours";

    else if(num>=60.0 && num<70.0)

    cout<<"Upper Second Class Honours";

    else if(num>=50.0 && num<60.0)

    cout<<"Lower Second Class Honours";

    else if(num>=40.0 && num<50.0)

    cout<<"Third Class Honours";

    else if(num<40.0)

    cout<<"Not an honours degree";

    }

    else

    {

    cout<<"Marks input is invalid";

    }

    }


    Is it good? ..
    Could it be improved?
