c++ initialize 2d vector with values code example
Example 1: initialize 2d vector of ints c++
auto M = 4;
auto N = 3;
auto default_value = 1;
std::vector<std::vector<int>> matrix(M, std::vector<int>(N, default_value));
Example 2: initializing 2d vector
vector<vector<int> > vec( n , vector<int> (m, 0));
Example 3: initialzing a 2d vector in cpp
vector<vector<int> > vec( n , vector<int> (m, 0));
Example 4: initialise 2d vector in c++
vector<vector<int> > vect{ { 1, 2, 3 },
{ 4, 5, 6 },
{ 7, 8, 9 } };
