# If-Else Conditions

The if construction may also contain an else clause to give a specific action in case the boolean expression (which is set at the beginning if (boolean expression) ) returns a negative result (false). Built this way, the conditional statement is called if-else and its behavior is as follows: if the result of the condition is positive (true) - we perform some actions, when it is negative (false) - others. The format of the construction is:

if (condition)
{
// condition body;
}
else
{
// еlse construction body;
}


## Example: Excellent Grade or Not

Like the example above, we read the grade from the console and check if it's excellent, but this time we should output the result in both cases.

## About the Curly Braces {} After If / Else

When we have only one command in the body of the if construction, we can skip the curly brackets, indicating the conditional operator body. When we want to execute block of code (group of commands), curly brackets are required. In case we drop them, only the first line after the if clause will be executed.

 It's a good practice to always put curly braces, because it makes our code more readable and clean.

Here is an example where dropping curly braces leads to confusion:

Executing the above code will output the following console result:

With curly braces:

The following output will be printed on the console:

## Example: Even or Odd Number

Write a program that checks whether an integer is even or odd.

We can solve the problem with one if-else statement and the operator %, which returns a remainder by dividing two numbers.

## Example: The Larger Number

Write a program that reads from the console two integers and takes the larger of them.

Our first task is to read the two numbers from the console. Then, with a simple if-else statement, combined with the operator for greater than (>), we do check. Part of the code is deliberately blurred, so you can test what you learned so far.
