Question

Provide an example of a nested block-structure control-flow structure consisting of  

• at least one for loop

• at least one signed and unsigned comparison which don't check for (in)equality. (<, <=, >, or >= are all fine)

• at least one other block-structured control-flow idiom (i.e., if/else, while, or do/while)

And a linearization of it to goto-c, including clear annotation as to why it is correct.

Answer 1

int i=0;

LOOP: for(i=0;i<10;i++)

{ //nesting level 1

if(i==0)

{

i=i+1;

goto LOOP;

}

else

    { // nesting level 2

        if ((i% 2) == 0)

        { // nesting level 3

           printf("even");

        }

        else

        { // also nesting level 3

printf("odd");

        }

    }

}
