Control Flow

Conditional Statements

If / else

if (condition)
  // Statement
else if (anotherCondition)
{
  // Another statement
}
else
{
  // Yet another statement
}

Switch / case

switch(variable)
{
  case "A":
  case "B":
    // Do something
    break;
  case "C":
    // Do something
    break;
  default:
    // Do something
    break;
}

Conditional operator

bool isGoldCustomer = true;
float price = (isGoldCustomer) ? 19.95f : 29.95f;

Iteration Statements

For loops

for (var i = 0; i < 10; i++)
{
  // Do something 10 times
}

Foreach loops

Iterates over elements of a numerical object. In other words, it has a list nature--like arrays or strings.

foreach (var number in numbers)
{
  // Do stuff
}

While loops

while (true)
{
  // Do something infinitely
}

Do-while loops

The only difference with a do-while loop is that the code block is executed at least once because the condition is always checked after the code block runs.

do
{
  // Something
} while (i < 10);

Break and continue

For any of these control flow statements, we have access to the break and continue keywords. break will break out of the loop or flow. continue will move onto the next iteration.
