This document outlines an agenda for a C# programming course covering loops, arrays, and different loop structures like for, while, and do-while loops. It provides examples of how to use for loops to iterate through numbers and print them, and explains that arrays allow storing multiple variables of the same type together. As homework, students are asked to write a program that prints incrementing stars in each line to create a triangle shape.

2. Agenda
• Loops
• For loop
• While & do while loop
• Arrays

3. Loops
• To repeat something many times in specific function
• What is the meaning of loops ?? and how we use it ??

4. For loop
For (start ; end ; step)
{
Do some thing
}
Example
For (Int i=0; i<10 ; i++)
{
Console.WriteLine(i);
}

5. While
While (Condition)
{
Do some thing
}

6. Do While
Do
{
Instructions …..
}
While (Condition)

7. Question … ???
What is the difference between While and
Do while ???

8. Array
a lot of variables of the same type in one place.

9. Home Work
