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.)

- Printf prototype int printf( const char. format. ); The printf function writes the string pointed to by format to stdout. The string format may contain format specifiers starting with% which are replaced by the values of variables that are passed to the printf function as additional arguments. It is defined in header file.
- Those listed here are supported by the latest C and C standards (both published in 2011), but those in yellow were introduced by C99 (only required for C implementations since C11), and may not be supported by libraries that comply with older standards. See also fscanf Read formatted data from stream (function ) printf.
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.
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.if constexpr statements

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):
