control structure
'''Control structures''' are constructs used to control the logic of a program based on a given condition. . . . Control structures typically use [[branch]] or [[loop]] statements. Code is typically . . . within the control structure. === _Conditional Branching_ The following example shows a [[block]] . . . of code being used as a conditional [[branch]]: {{{ awk if (guess == 6) { print "Wow!
