C# Loops

In programming, we use Loops when executing a block of code more than once. Loops allow programmers to execute a set of code sequentially provided a given condition is true. Like most programming languages, C# allows us to utilize loops in our programs. The illustration below shows the structure of a loop in programming.

C# has two main types of loop statements and two secondary loop statements. They include:

❖ For loop

❖ While loop

❖ do…while loop

❖ nested loops

1: The For loop

The for loop is a statement used to perform a certain condition a specific number of times. C# for loop statement is very similar to that of C and C++. The syntax for the for loop is:

for (initialization; condition; loop_counter) {

// condition statement

}

The first step, initialization, initializes the loop that includes loop control variable declaration and initialization.

The second step, condition, sets the condition that the loop will use to evaluate which code will execute. If the condition is true, the code inside the curly braces executes. Otherwise, perform another action.

The third step is the loop counter. We use the loop counter to update the condition per each iteration. The loop counter utilizes the unary operators for loop update.

The following is a summary of how the for loop works

The initialization step runs only once.
