rec.cpp

经典c++程序的实现

//typedef double DataType; 

#include <stdio.h>
#include <assert.h>
#include <iostream.h>

typedef double ELEM;             // calculator accepts real data

#include "..\include\book.h"
#include "..\include\astack.h"

void exmp(int n, int& f) {
	int u1, u2;

	if (n<2)
		f = n+1;
	else {
        exmp((int)(n/2), u1);
		exmp((int)(n/4), u2);
        f = u1*u2;
	}
}

void main(void)  {
	int func;

    exmp(37, func);
	cout << func << endl;
}
