resize two dimensional vector c++
//vector<vector<int>> M;
//int m = number of rows, n = number of columns;
M.resize(m, vector<int>(n));resize two dimensional vector c++
//vector<vector<int>> M;
//int m = number of rows, n = number of columns;
M.resize(m, vector<int>(n));when a vector in c++ is resized what happens to the elements of the vector
The C++ function std::vector::resize() changes the size of vector. If n is smaller than current size then extra elements are destroyed.
If n is greater than current container size then new elements are inserted at the end of vector.
If val is specified then new elements are initialed with val.c++ vector resize
std::vector<int> vec = {1, 2, 3};
vec.resize(2); // {1, 2}
vec.resize(4); // {1, 2, 0, 0,}
vec.resize(6, 9); // {1, 2, 0, 0, 9, 9}Copyright © 2021 Codeinu
