fstream 输入的基本用法（供个人备忘）

#include <fstream>
#include <iostream>
#include <string>

using namespace std;

int main(int argc, char **argv)
{
ifstream fin("map.txt");
int width = 21;
int height = 19;
char *mapInfo = new char[width * height];
int cntLine = 0;
while(!fin.eof()){
string line;
getline(fin,line);
for(int j = 0;j < width;j++)
mapInfo[cntLine * width + j] = line[j];
cntLine++;
}
cout << "MapInfo : " << endl;
for(int i = 0;i < height;i++){
for(int j = 0;j <width;j++){
cout << mapInfo[i * width + j];
}
cout << endl;
}
fin.close();
return 0;
}
