所以我有一个包含三列的文件,例如:
1 1 750
这些是 x,y,强度值。
然后我尝试将这个长文件读入数组。这是到目前为止的代码:
using std::cout;
using std::endl;
using std::string;
string fOutFileName("gaintest.root");
int main()
{
std::ifstream file1("data_p30.dat");
double intensity;
int i;
int j ;
double c[1000][1000];
if (file1.is_open()) {
file1.seekg(0);
while (!file1.eof()) {
file1 >> i >> j >> intensity;
c[i][j]=intensity;
cout<<c[i][j]<<'/n';
}
file1.close();
} else cout << "Error, cannot open file 1";
}
所以最终我希望能够拥有一个与强度相关的二维数组。关于我为什么失败的任何想法?它编译得很好,但是当它运行时,它看起来像这样:
root [0]
