C# For Loop

Syntax

for(initialization; condition; increment/decrement)
{
   // code to be executed
}

Example

for (int i = 0; i < 5; i++)
{
   Console.WriteLine(i);
}

Output

0
1
2
3
4

Explanation

The for loop is used in C# to repeatedly execute a block of code based on a condition. The for loop is initialized with a counter variable and an expression that evaluates to a Boolean value. If the expression is true, the loop body is executed. After the loop body is executed, the counter variable is incremented or decremented.

In the example above, the loop is initialized with the counter variable i. The loop body executes as long as the value of i is less than 5. After each iteration of the loop body, the value of i is incremented by 1. When the value of i is equal to 5, the loop terminates.

Use

The for loop is very common in C# programs and is used to iterate through arrays or loops. It can also be used to repeat a block of code a fixed number of times. The for loop is often used where the number of iterations is known in advance.

Important Points

• The for loop is used to repeatedly execute a block of code based on a condition.
• The for loop is initialized with a counter variable and an expression that evaluates to a Boolean value.
• The loop body is executed as long as the expression is true.
• After the loop body is executed, the counter variable is incremented or decremented.
• The for loop is often used where the number of iterations is known in advance.

Summary

In C#, the for loop is used to repeatedly execute a block of code based on a condition. The for loop is initialized with a counter variable and an expression that evaluates to a Boolean value. It is often used to iterate through arrays or loops and can be used to repeat a block of code a fixed number of times. It is an important construct in any C# program.
