For each object you print using cout, figure out the type and put it in a format string. String literals go into the format string as is, and in order. In your case, the types are int (for x) and double (for the return type of pow), so you would have something like this:

/* cout<<x<<" "<< pow (2,x)<<endl; */
printf ( "%d %f\n", x, pow ( 2, x ) );

Simply printing a newline is sufficient to flush in C, so no extra work is necessary (unlike with endl in C++).

p.s. If that's the only line you change, you'll have more errors when compiling as C.
