    Study Notes

    Infinite Loops

    In C#, an infinite loop is a type of while loop that continues to execute indefinitely until it is manually terminated.

    Characteristics:

    • The loop condition is always true
    • The loop body is executed repeatedly without stopping
    • Can be useful for tasks that need to run indefinitely, such as:
      • Monitoring system resources
      • Listening for network connections
      • Handling user input

    Example of an Infinite Loop:

    while (true)
{
    Console.WriteLine("Hello, world!");
}

    This loop will continue to print "Hello, world!" to the console indefinitely until the program is stopped.

    Caution:

    • Infinite loops can cause programs to consume excessive resources, leading to performance issues or even crashes
    • Use infinite loops with caution and consider implementing mechanisms to break out of the loop when necessary

    Breaking out of an Infinite Loop:

    • Use the break statement to exit the loop prematurely
    • Use a conditional statement to check for a specific condition and exit the loop when met
    • Use a return statement to exit the method or function

    Example:

    bool exitLoop = false;
while (true)
{
    Console.WriteLine("Hello, world!");
    if (exitLoop)
    {
        break;
    }
}

    Infinite Loops

    • An infinite loop is a type of while loop that continues to execute indefinitely until manually terminated.
    • The loop condition is always true, and the loop body is executed repeatedly without stopping.

    Uses of Infinite Loops

    • Useful for tasks that need to run indefinitely, such as:
      • Monitoring system resources
      • Listening for network connections
      • Handling user input

    Characteristics of Infinite Loops

    • Can cause programs to consume excessive resources, leading to performance issues or even crashes
    • Requires caution and consideration of mechanisms to break out of the loop when necessary

    Breaking out of Infinite Loops

    • Use the break statement to exit the loop prematurely
    • Use a conditional statement to check for a specific condition and exit the loop when met
    • Use a return statement to exit the method or function
    • Example: using a boolean flag to exit the loop when a condition is met
