c++从文件中读取一行数据并保存在数组中

从txt文本中读取数据存入数组中

 #include <iostream>
 #include <fstream>
 #include <string>
 #include <vector>
 using namespace std;
 
 int main()
 {
     ifstream infile;
     infile.open("1.txt");
     if(!infile) cout<<"error"<<endl;
 
     string str;
     int t1;
 /*  while(getline(infile,str))   //按行读取,遇到换行符结束
     {
         infile.getline(str,10);
         cout<<str<<endl;
     }
 */
  /*//存入vector
     cout<<"存入vector"<<endl;
     vector<int> ve;
     while(infile>>t1)             //按空格读取，遇到空白符结束
     {
         ve.push_back(t1);
     }
 
     for(int i=0;i<ve.size();i++)
         cout<<ve[i]<<" ";
     cout<<endl;
 */
 
 //存入数组
     cout<<"存入数组"<<endl;
     int a[][];
     int*p=&a[][];
     while(infile>>t1)             //遇到空白符结束
     {
         *p=t1;
          p++;
     }
     infile.close();
     for(int i=;i<;i++)
     {   for(int j=;j<;j++)
            cout<<a[i][j]<<"\t";
          cout<<endl;
     }
     return ;
 }
