Alternatives to multilevel breaks include single breaks, together with a state variable which is tested to break out another level; exceptions, which are caught at the level being broken out to; placing the nested loops in a function and using return to effect termination of the entire nested loop; or using a label and a goto statement.

Hitting the Enter key adds ";" to the end of the line implicitly (does not show up in the source code). The left curly bracket {cannot come at the start of a line. [59]
Probably the most famous criticism of GOTO is a 1968 letter by Edsger Dijkstra called "Go-to statement considered harmful". [3] In that letter, Dijkstra argued that unrestricted GOTO statements should be abolished from higher-level languages because they complicated the task of analyzing and verifying the correctness of programs (particularly ...
A language that supports the statement construct typically has rules for one or more of the following aspects: Statement terminator – marks the end of a statement; Statement separator – demarcates the boundary between two statements; need needed for the last statement; Line continuation – escapes a newline to continue a statement on the ...
