2d array passing as an argument c++ code example
Example: passing a 2d array cpp
#include <iostream>
#include <vector>
using namespace std;
typedef vector< vector<int> > Matrix;
void print(Matrix& m)
{
int M=m.size();
int N=m[0].size();
for(int i=0; i<M; i++) {
for(int j=0; j<N; j++)
cout << m[i][j] << " ";
cout << endl;
}
cout << endl;
}
int main()
{
Matrix m = { {1,2,3,4},
{5,6,7,8},
{9,1,2,3} };
print(m);
//To initialize a 3 x 4 matrix with 0:
Matrix n( 3,vector<int>(4,0));
print(n);
return 0;
}
