  2. Assignment (computer science) - Wikipedia

    en.wikipedia.org/wiki/Assignment_(computer_science)

    In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct.

  3. Statement (computer science) - Wikipedia

    en.wikipedia.org/wiki/Statement_(computer_science)

    Simple statements are complete in themselves; these include assignments, subroutine calls, and a few statements which may significantly affect the program flow of control (e.g. goto, return, stop/halt). In some languages, input and output, assertions, and exits are handled by special statements, while other languages use calls to predefined ...

  4. Ternary conditional operator - Wikipedia

    en.wikipedia.org/wiki/Ternary_conditional_operator

    For example, to pass conditionally different values as an argument for a constructor of a field or a base class, it is impossible to use a plain if-else statement; in this case we can use a conditional assignment expression, or a function call. Bear in mind also that some types allow initialization, but do not allow assignment, or even that the ...

  5. Conditional operator - Wikipedia

    en.wikipedia.org/wiki/Conditional_operator

    Special usage in assignment expression [ edit ] the conditional operator can yield a L-value in C/C++ which can be assigned another value, but the vast majority of programmers consider this extremely poor style, if only because of the technique's obscurity.

  6. Expression-oriented programming language - Wikipedia

    en.wikipedia.org/wiki/Expression-oriented...

    The designers of Ada and Java prevent this type of mistake by restricting control expressions to those that evaluate strictly to the boolean data type. [5] [6] The designers of Python implemented assignment as a statement rather than an expression, thus prohibiting assignment from nesting inside any other statement or expression. [7] (Until ...

  7. Augmented assignment - Wikipedia

    en.wikipedia.org/wiki/Augmented_assignment

    Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C).An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.

  8. Operator associativity - Wikipedia

    en.wikipedia.org/wiki/Operator_associativity

    In many imperative programming languages, the assignment operator is defined to be right-associative, and assignment is defined to be an expression (which evaluates to a value), not just a statement. This allows chained assignment by using the value of one assignment expression as the right operand of the next assignment expression.

  9. Operator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Operator_(computer...

    For example, in assignment a = b the target a is not evaluated, but instead its location (address) is used to store the value of b – corresponding to call-by-reference semantics. Further, an assignment may be a statement (no value), or may be an expression (value), with the value itself either an r-value (just a value) or an l-value (able to ...
