2d array function

[qwe123]

Hi,

I am trying to build a 2D matrix and fill the first row and column with zeros. However, I want to do this in a function, but I have huge problems doing this.

The following code works, but this is hardcoded. Alternative solutions are also welcome :)


#include <iostream>
#include <string>

using namespace std;

void fill_matrix(int L1,int L2,int array[][6]) {
for (int i=0;i<L1;i++)
{
array[i][0] = 0;
}
for (int j=0;j<L2;j++)
{
array[0][j] = 0;
}
}

int main() {
int L1,L2;
string seq1,seq2;
seq1 = "actgc";
seq2 = "agtgt";
L1 = seq1.size()+1;
//L2 = seq2.size()+1;
L2 = 6;
int M[6][6];
fill_matrix(L1,L1,M);

return 0;
}

int test2[2][2] = { {0} };
std::copy(test2[0], test2[0] + 4, std::ostream_iterator<int>(cout, ", "));
cout<<endl;

sorry, I forgot to change the contents of test2

if you want to fill the array with another number

int test2[2][2];
std::fill(test2[0], test2[0] + 4, 10);
std::copy(test2[0], test2[0] + 4, std::ostream_iterator<int>(cout, ", "));
cout<<endl;
