Two dimensional strings in C++
- by dada
I want to write something like 2d strings in C++.
I tried with :
vector< vector<string> > table;
int m,n,i,j;
string s;
cin>>n>>m;
for(i=0;i<n;i++) {
for(j=0;j<m;j++) {
cin>>s;
table[i][j] = s;
}
}
cout << "\n\n\n\n";
for(i=0;i<n;i++) {
for(j=0;j<m;j++) {
cout<<table[i][j]<<" ";
}
cout<<"\n";
}
no compile errors, but when i enter input like:
10 20
.....#..............
.....#..............
.....#..............
.....#..............
######..............
.......###..........
.......#.#..........
.......###...#######
.............#.....#
.............#######
It gives me segmentation fault. Why ? What's wrong ? And how it should be done so it would work correctly ? Thank you.
