SOLVED Computer Science 1081 Assignment 05

Program    #1 &    #2 (NOTE:    TWO    DIFFERENT    PROGRAMS)
The    distance    a    vehicle    travels    can    be    calculated    as    follows:    distance    =    speed    *    time.        For    
example,    if    a    train    travels    40    miles    per    hour    for    3    hours,    the    distance    traveled    is    120    miles.        
Write    a    program    that    asks    the    user    for    the    speed    of    a    vehicle    (in    miles    per    hours)    and    how    many    
hours    it    has    traveled.        The    program    should    then    use    a    loop    to    display    the    distance    the    vehicle    
has    traveled    for    each    hour    of    that    time    period.        Do    not    accept    a    negative    number    for    speed    and    
do    not    accept    any    value    less    than    1    for    time    traveled.
• Program    #1:    Write    only    using    while    loops
• Program    #2:    Write    only    using    do-while    loops
• Program    should    loop    until    the    user    enters    correct    data [INPUT    VALIDATION]
Sample    Output:
What is the speed of the vehicle in mph? 50
How many hours has it traveled? -4
How many hours has it traveled? 4
Hour Distance Traveled
-------------------------------
 1 50
 2 100
 3 150
 4 200

Program    #3
Write    a    program    that    calculates    how    much    a    person    would    earn    over    a    period    of    time    if    his    or    
her    salary    is    one    penny    the    first    day    and    two    pennies    the    second    day,    and    continues    to    double    
each    day.        The    program    should    ask    the    user    for    the    number    of    days.        Display    the    table    showing    
how    much    the    salary    was    for    each    day,    and    then    show    the    total    pay    at    the    end    of    the    period.        
The    output    should    be    displayed    in    a    dollar    amount,    not    the    number    of    pennies.        Do    not    accept    a    
number    less    than    1    for    the    number    of    days    worked.    
• Use    a    do-while    loop    for    input    validation
• Use    a    for    loop    to    calculate    the    pay    increase    and    display    the    table
Sample    Output:
For how many days will the pay double? 6
Day Total Pay
---------------------
 1 $ 0.01
 2 $ 0.02
 3 $ 0.04
 4 $ 0.08
 5 $ 0.16
 6 $ 0.32
---------------------
Total $ 0.63

Program    #4
Write    a    program    that    uses    nested    loops    to    collect    data    and    calculate    the    average    rainfall    over    a    
period    of    years.        The    program    should    first    ask    for    the    number    of    years.        The    outer    loop    will    
iterate    once    for    each    year.        The    inner    loop    will    iterate    twelve    times,    once    for    each    month.        Each    
iteration    of    the    inner    loop    will    ask    for    the    inches    of    rainfall    for    that    month.    
After    all    iterations,    the    program    should    display    the    number    of    months,    the    total    inches    of    
rainfall,    and    the    average    rainfall    per    month    for    the entire    period.        Do    not    accept    a    number    less    
than    1    for    the    number    of    years.        Do    not    accept    negative    number    for    the    monthly    rainfall.
• Input    validation    not    required
• Only    use    for    loops    and    nested    loops    for    computation
• Use    a    const for    the    number    of    months    in    the    year.    (for    ease    of    testing    interactively,    
consider    a    calendar    with    only    4    months    in    a    year,    your    program    should    be    able    to    work    
by    just    changing    this    constant)
Sample    Output:
This program will calculate average rainfall over a
period of years. How many years do you wish to average? 2
Year 1
