size of 2d array in c++
int rows = sizeof(arr) / sizeof(arr[0]); // returns rows
int col = sizeof(arr[0]) / sizeof(int); // returns colsize of 2d array in c++
int rows = sizeof(arr) / sizeof(arr[0]); // returns rows
int col = sizeof(arr[0]) / sizeof(int); // returns colhow to get size of 2d vector in c++
myVector[
Vector[0, 4, 2, 5],
Vector[1, 4, 2]
];
/*When you call for myVector[1].size() it would return 3 and [0] would return 4.
For the amount of rows (int vectors) in the 2d vector, you can just use myVector.size()
You can run this to see it in actions*/Copyright © 2021 Codeinu
