Examples
Below are examples of loops in C#
// Do-While Loop: This type of loop will always run at least once because it will not check the termination condition until after the first run.
string choice; // This will be used to store the user's input.
bool validSelection; // This will be used to terminate the loop.
do
{
console.WriteLine("Which path will you take? 1 or 2?"); // prompt for asking the user.
choice = console.ReadLine(); // getting the user's input.
if(choice == "1" || choice == "2") // checking to see if the choice is valid.
{
validSelection = true; // valid choice, no longer need to loop.
}
else
{
validSelection = false; // invalid choice. Because the variable is set to false, it will cause the loop to repeat, meaning that the user will be asked to make a choice again.
}
} while(validSelection == false) // if validSelection is set to false, repeat the loop.
// For Loop: This type of loop will run the specified number of times. Typically used for iterating through collections such as arrays or lists.
string[] contactNames = {Adam, Ben, Charile, Derek, Erik, Frank };
for(int i = 0; i < contactNames.Length; i++)
{
}
