Q1: What is the difference between the following two statements:

1. if (n > 2) { if (n < 6) cout << “OK”; } else cout << “NG”;

2. if (n > 2) { if (n < 6) cout << “OK”; else cout << “NG” };

------------------------
Q2: Use switch statement to rewrite the following code segment:

if (num == 1)
{cout << “Alpha”; }
else if (num == 2)
{ cout << “Beta”; }
else if (num == 3)
{ cout << “Gamma”; }
else
{ cout << “Other”; }
--------------------------
Q3: A palindrome is a number or a phrase that reads the same backwards as
forwards. For example, each of the following five-digit integers is a palindrome:
12321, 55555, 45554 and 11611. Write a program that reads in a five-digit integer
and determines whether it is a palindrome.
-----------------------
Q4: Write a program that reads three nonzero integers and determines and prints
whether they could be the sides of a right triangle.
----------------------
Q5: Write and run a program –using nested if- that plays the game of "rock, paper,
scissors.”

The rules are:
1. Paper dominates (wraps) rock
2. Rock dominates (breaks) scissors
3. Scissors dominate (cut) paper

Hints:
• The program must clear the screen after the first player makes his/her choice; the
second player should not know his/her choice.
• The program must clear the screen after the second player makes his/her choice,
and then print the result.
•
Output samples:

Try 1:

* Welcome to "rock, paper, scissors.” Game *

st
1 Player
Please enter your first name: Abdullah

Choose rock (0), paper (1), or scissors (2):

Abdullah: 1
* Welcome to "rock, paper, scissors.” Game *

nd
2 Player
Please enter your first name: Ahmad

Choose rock (0), paper (1), or scissors (2):

Ahmad: 0

Abdullah chose paper
Ahmad chose rock
########## Abdullah WINS ##########

6-Write and run a program that print the following table:
Monthly Sales Income
--------------------------------------------------------------------------------------------------------------------
Greater than or equal to $50,000 $375 plus 16% of sales
Less than $50,000 but greater than or equal to $40,000 $350 plus 14% of sales
Less than $40,000 but greater than or equal to $30,000 $325 plus 12% of sales
Less than $30,000 but greater than or equal to $20,000 $300 plus 9% of sales
Less than $20,000 but greater than or equal to $10,000 $250 plus 5% of sales
Less than $10,000 $200 plus 3% of sales

Then calculates the monthly income of a computer salesperson using the following
commission schedule:

Monthly Sales Income
--------------------------------------------------------------------------------------------------------------------
Greater than or equal to $50,000 $375 plus 16% of sales
Less than $50,000 but greater than or equal to $40,000 $350 plus 14% of sales
Less than $40,000 but greater than or equal to $30,000 $325 plus 12% of sales
Less than $30,000 but greater than or equal to $20,000 $300 plus 9% of sales
Less than $20,000 but greater than or equal to $10,000 $250 plus 5% of sales
Less than $10,000 $200 plus 3% of sales
--------------------------------------------------------------------------------------------------------------------
Enter the value of monthly sales: 36243.89
The income is $4674.27

بليز احد يساعدني وربي محتاس للاخر

هذي حل السؤالين الأولى:


Q1: What is the difference between the following two statements:

1. if (n > 2) { if (n < 6) cout << “OK”; } else cout << “NG”;

2. if (n > 2) { if (n < 6) cout << “OK”; else cout << “NG” };

------------------------
الخيار الأول else تابعة لـ If الأولى وif الثانية اللي بين قوسين كبيرة برضها تابعة للـ if الأولى بس مالها علاقة ب else
الخيار الثاني else تابعة لـ if الثانيــــــة واللي هي بدورها تابعة لكلمة if الأولى يعني ما راح تتطبق إلا لما ينطبق شرط أول if ويختل شرط ثاني if

يعني مثلاً إذا دخلت 1
الخيار الأول :ما راح يدخل على if فيروح المعالج على طول على else ويكتب لي NG

الخيار الثاني : ماراح يدخل على أول if ,, وعشان if الثانية هي وelse من ضمن الستيتمنت حقتها ف اختل الشرط من البداية وما راح يكتب لي شيء.



-------------------------------------
Q2: Use switch statement to rewrite the following code segment:

if (num == 1)
{cout << “Alpha”; }
else if (num == 2)
{ cout << “Beta”; }
else if (num == 3)
{ cout << “Gamma”; }
else
{ cout << “Other”; }

الجواب:

switch(num)
case 1: cout<<"Alpha"; break;
case 2 : cout<<"Beta"; break;
case 3 : cout<<"Gamma" ; break;
default: cout<<"Other" ;
break;

هذا اللي خطر على بالي عالسريع

بالتوفيق
