C# Concepts

 Q1)What is Difference between  For Loop and For-Each Loop in C#?

• For loop iterates a statement or a block of statements repeatedly until a specified expression evaluates to false.
•  For-each loop is used to iterate through the items in object collections, List generic collections or array list collections. 
• Performance: For Loops are faster than For-each Loop. If we iterate array list or any collection with for loop and for-each loop then you will find time consumed by a for-each loop is much more than for loop so For loops are faster than For-each loop.

Q2) What is mean by Conditional statement? 

Ans: A block of code that gets executed basis on a condition is known as conditional Statement. These are of two types:

•  Conditional Branching
•  Conditional Looping.

Q3)What is mean by Conditional Branching? 

Ans: These statements allow us to branch our code depending on whether certain condition was met or not. C# has two constructs for branching code

•  If 
• Switch

Q4)What is mean by Conditional Looping?

Ans: C# provides three different loops that allows us to execute a block of code repeatedly until a certain condition is met, those are 

• For Loop 
• While Loop 
• Do While Loop

 Every Loop requires three things in common. 

1. Initialization: That sets the starting point of the loop. 
2. Condition: That sets the ending point of the loop. 
3. Iteration: Which takes you to the next level of the cycle either forward or backward direction.
