Groups:: Program Flow

Syntax:

ifType then thenCode

Parameters:

ifType: If Type

thenCode: Code or Array of Code. Can be one of:

Code - code block to execure if ifType's condition is true
Array of Code- array of two code elements in format [thenCode, elseCode]; see Example 3

Return Value:

Anything - result of the executed code

Example 1:: if (a > b) then { hint "a is greater than b!"; };
Example 2:: private _c = 0; if (a > b) then { _c = 1; } else { _c = 2; };
