Within an imperative programming language, a control flow statement is a statement that results in a choice being made as to which of two or more paths to follow. For non-strict functional languages, functions and language constructs exist to achieve the same result, but they are usually not termed control flow statements.
Control is checking current performance against pre-determined standards contained in the plans, with a view to ensuring adequate progress and satisfactory performance. According to Harold Koontz: Controlling is the measurement and correction of performance to make sure that enterprise objectives and the plans devised to attain them are ...
Some CFG examples: (a) an if-then-else (b) a while loop (c) a natural loop with two exits, e.g. while with an if...break in the middle; non-structured but reducible (d) an irreducible CFG: a loop with two entry points, e.g. goto into a while or for loop A control-flow graph used by the Rust compiler to perform codegen.
Some languages may use a different naming convention for this type of loop. For example, the Pascal and Lua languages have a "repeat until" loop, which continues to run until the control expression is true and then terminates. In contrast a "while" loop runs while the control expression is true and terminates once the expression becomes false.
In other languages, it is also possible to assign functions as lookup table values, gaining the same flexibility as a real switch statement. See Control table article for more detail on this). Lua does not support case/switch statements. [15] This lookup technique is one way to implement switch statements in the Lua language, which has no built ...
Although control was one of the six 'functions of management' [9] listed by Henri Fayol in 1917, [10] [11] the idea of strategic control as a distinct activity does not appear in the management literature until the late 1970s (e.g. "Strategic Control: a new task for top management" by J H Horovitz, [12] which was published in 1979, is a candidate for first paper to explicitly discuss the topic ...

Some researchers have criticised control self-assessment as a flawed approach as the way risk is defined and measured is unsophisticated. In particular, control self-assessment may understate risk by not identifying extreme downside risk. An extreme downside risk is a highly improbable event that would have catastrophic consequences if it occurred.
