Using Goto function across different functions

Question

How can I use goto function across different functions .For ex ,

    main()

      ....
      REACH:
      ......
    }

    void function()
    {
             


        

Answer 1

You can't in Standard C++. From $6.6.4/1 of the C++ Language Standard

The goto statement unconditionally transfers control to the statement labeled by the identifier. The identifier shall be a label (6.1) located in the current function.

...or in Standard C. From $6.8.6.1/1 of the C Language Standard

The identifier in a goto statement shall name a label located somewhere in the enclosing function. A goto statement shall not jump from outside the scope of an identifier having a variably modified type to inside the scope of that identifier.
