Question

C++ Vectors

readImage: Creates a two dimensional vector (a matrix) of 1's and 0's based off of the input files which you send it. (Returns a multidimensional vector). Take two inputs - number of columns and number of rows.The image stored in a two-dimensional vector of ints.

printImage: Takes the matrix which was created in readImage and prints it out.

vector <vector<int>> readImage(int,int);

void printImage (vector<vector<int>>);

input: (explained in ()'s )

1 -(input 1)
10 1  - (10 colums and 1 row)
1 0 0 1 1 1 1 0 1 1   -(this needs to be outputed)

output:

1001111011

Answer 1

vector<vector<int> > readImage(int r, int c){
   vector<vector<int> > v;
   for(int i=0;i<r;i++){
       vector<int> temp;
       for(int j=0;j<c;j++){
           int x;
           cin >> x;
           temp.push_back(x);
       }
       v.push_back(temp);
   }
   return v;
}

void printImage(vector<vector<int> > v){
   for(int i=0;i<v.size();i++){
       for(int j=0;j<v[i].size();j++){
           cout << v[i][j] << " ";
       }
       cout << endl;
   }
}
