Copy the code into a new function. Then see what parameters this function
needs for the various information it requires. The code will produce some
results that are needed by the rest of the program. So you have to
arrange via the return value that the proper variables are initialized
after the function call.
For example,
x = a + b;
could become
int f(int a, int b) {
return a + b;
}
x = f(a,b);
That is a pretty silly change, but it gives the idea.
