A control variable in computer programming is a program variable that is used to regulate the flow of control of the program .[1]


A loop control variable is used to regulate the number of times the body of a program loop is executed; it is incremented (or decremented when counting down) each time the loop body is executed. A single control variable can identify the present state of a computer program.
