When you start to learn a programming language such as C#, one of the most important concepts is Flow Control. In such a case, switch statements are your friend they take a single expression/value as an input, and then look through several choices until they find one that matches that value, executing the corresponding code that goes along with it.

Use else if to specify a new condition to test, if the first condition is false. Conditional Statements in C programming are used to make decisions based on the conditions. days = 30; These statements are formed by combining two statements, which are called compound statements.

If statement and switch statements are the examples of conditional controls statements which executes based on the given condition. The if-else statement in C language is used to execute the code if the condition is true or false. It is very helpful and useful in making conditional decisions based on our program. (In other words, upon reaching break, execution will jump past your entire code snippet, since all of the snippet is contained within the for loop.) In Python, the boolean class is called 'bool'. For example, in a game, if the player's number of lives is 0, then it's game over.

When used in conditions, the first two do the following: To give you an AND example, the previous example snippet can be rewritten to this: So for example, the first code block will only be run if choice === 'sunny' and temperature < 86 return true. The following example executes the code inside only if both OR statements return true, meaning that the overall AND statement will return true: A common mistake when using the logical OR operator in conditional statements is to try to state the variable whose value you are checking once, and then give a list of values it could be to return true, separated by || (OR) operators.
