 An if-else statement controls conditional branching. Statements in the *`if-branch`* are executed only if the *`condition`* evaluates to a non-zero value (or **`true`**). If the value of *`condition`* is nonzero, the following statement gets executed, and the statement following the optional **`else`** gets skipped. Otherwise, the following statement gets skipped, and if there's an **`else`** then the statement following the **`else`** gets executed.

+In all forms of the **`if`** statement, *`condition`*, which can have any value except a structure, is evaluated, including all side effects. Control passes from the **`if`** statement to the next statement in the program unless the executed *`if-branch`* or *`else-branch`* contains a [`break`](../cpp/break-statement-cpp.md), [`continue`](../cpp/continue-statement-cpp.md), or [`goto`](../cpp/goto-statement-cpp.md).

+The **`else`** clause of an `if...else` statement is associated with the closest previous **`if`** statement in the same scope that does not have a corresponding **`else`** statement.

 ## <a name="if_constexpr"> if constexpr statements
 
 Starting in C++17, you can use an **`if constexpr`** statement in function templates to make compile-time branching decisions without having to resort to multiple function overloads. **Microsoft-specific**: This form is available starting in Visual Studio 2017 version 15.3, and requires at least the [`/std:c++17`](../build/reference/std-specify-language-standard-version.md) compiler option.
