我需要帮助为多个.hpp和.cpp文件创建一个正确的makefile(支持增量编译).

我一直在寻找有关如何创建正确的makefile的信息,但我不确定如何做到这一点.

我有以下文件:2048.cpp,game.cpp,game.hpp,gameutils.cpp,gameutils.hpp,menu.cpp,menu.hpp,saveandback.cpp,saveandback.hpp和tile.hpp

现在我正在使用以下makefile:

all: 2048.cpp tile.hpp menu.hpp menu.cpp gameutils.hpp gameutils.cpp saveandback.hpp saveandback.cpp game.hpp game.cpp
    g++ -g -W -Wall --pedantic -DNDEBUG 2048.cpp -o power

clean: 
    $(RM) power

谢谢您的帮助.

我想使用迭代器打印一个向量:

#include <vector>
#include <istream>
#include <iostream>
#include <sstream>
#include <stdlib.h>
#include <math.h>
using namespace std;

typedef vector<int> board;
typedef vector<int> moves;


int sizeb;
board start;
moves nmoves;
istringstream stin;


board readIn(std :: istream& in ) {
    int val;
    while (in >> val)
    start.push_back(val);

    sizeb = start[0];
    return start;
}


void printboard(board n) {
    int sizem = sizeb*sizeb;
    int i = 1;

    for (vector<int>::iterator it = start.begin() ; it != start.end(); ++it) {
        for (int j = 0; j < …
