cannot remove tne /n, because it will appear many times again

oooo..like that.thak you ancient dragon.

i dont know how to declare aTable. where to put it?

How to correct it?
ompiling...

	vector< vector<double> >table(ROWS, vector<double>(COLUMNS, 0.0));   // 10 zero-initialized ints
  unsigned int i;

  // assign some values:
    for (int row = 0; row < table.size(); row++)
    
{
    cout << "Examcode:";
    for (int col = 0; col < aTable[row].size(); col++)
    cout << setw(8) << table[row][col];
    cout << endl;
}
    return 0;
}

i need both of cout, but dont want it repeat each time of student...........

How can in the output, I want ONLY ONE LINE from 1 to 99, the windows is not enough..

myvector contains: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 5

#include <iostream>
#include <vector>
using namespace std;

int main ()
{
  vector<int> myvector (100);   // 10 zero-initialized ints
  unsigned int i;

  // assign some values:
  for (i=0; i<myvector.size(); i++)
    myvector.at(i)=i;

  cout << "myvector contains:";
  for (i=0; i<myvector.size(); i++)
    cout << " " << myvector.at(i);

  cout << endl;

  return 0;
}

How to make a correction, because I just want one line only.

whats the different between two multidimensional vector and array?

How to avoid the output for

20 appears 3 times.
repeat at each line. Im just want one only.

Hi,

can I combine int main() and void main() in 1 programming.??
