Box models of functions onef and twof follow. Do not try to define the complete functions; write only the portions described.

Assume that these functions are concerned only with integers, and write headings for onef and twof. Begin the body of function onef with a declaration of an integer local variable tmp. Show a call from onef to twof in which the input argument is dat, and tmp and out2p are the output arguments. Function onef intends for twof to store one integer result in tmp and one in the variable pointed to by out2p.
