#3

The statement vector< vector< int > > matrix(100, vector (50, 100) ) declares :

#4
  1. vector < int > (50, 100) declares a vector X of type int with 50 elements each initialized to 100 and matrix consists of 100 vectors of type int each equal to X. 2. The statement will result in a compile-time error. 3. vector (50, 100) declares a vector X of type int with 100 elements each initialized to 50 and matrix consists of 100 vectors of type int each equal to X. 4.The statement will result in a run-time error.
