The goto statement can be used to alter the flow of control in a program. Although the goto statement can be used to create loops with finite repetition times, use of other loop structures such as for, while, and do while is recommended. The use of the goto statement requires a label to be defined in the program.Which statement is true for goto statement?

Article first time published onIs goto faster than loop?
10 Answers. Generally speaking, for and while loops get compiled to the same thing as goto , so it usually won’t make a difference.

Answer: exit() is a system call which terminates current process. exit() is not an instruction of C language. Whereas, return() is a C language instruction/statement and it returns from the current function (i.e. provides exit status to calling function and provides control back to the calling function).
