For modular and structured programming, the c programming language is ideal. Even if a target language structure contains goto like statements it is often simpler and more efficient to deal with programs that have structured control flow to make the executable. It performs a oneway transfer of control to another line of code. So c incorporated the break statement to handle that problem. The participants were free to explore the model by dragging, zooming, and clicking on screen. A consideration of several different examples sheds new light on the problem of creating reliable, well structured programs that behave efficiently.

This is still in, but you can republish as much as you want noncommercially if you include the notice, cite the original publication, and note that permission to republish comes from the association for computing machinery. A goto statement in c programming provides an unconditional jump from the goto to a labeled statement in the same function note. Knuth stanford university, stanford, california 94305. Although the goto statement can be used to create loops with finite repetition times. Use of goto statement is highly discouraged in any programming language because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify.
