Controls conditional branching. Statements in the if-block are executed only if the if-expression evaluates to a non-zero value (or TRUE). If the value of expression is nonzero, statement1 and any other statements in the block are executed and the else-block, if present, is skipped. If the value of expression is zero, then the if-block is skipped and the else-block, if present, is executed. Expressions that evaluate to non-zero are

  • TRUE
  • a non-null pointer,
  • any non-zero arithmetic value, or
  • a class type that defines an unambiguous conversion to an arithmetic, boolean or pointer type. (For information about conversions, see Standard Conversions.)

Syntax

Example

if statement with an initializer

Visual Studio 2017 version 15.3 and later (available with /std:c++17): An if statement may also contain an expression that declares and initializes a named variable. Use this form of the if-statement when the variable is only needed within the scope of the if-block.

Example

In all forms of the if statement, expression, 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 one of the statements contains a break, continue, or goto.

Visual Studio 2017 version 15.3 and later (available with /std:c++17): In function templates, you can use an if constexpr statement to make compile-time branching decisions without having to resort to multiple function overloads. For example, you can write a single function that handles parameter unpacking (no zero-parameter overload is needed):
