An example code is given below to demonstrate how an array is created in Python. fromarrayimportarray temp_array=array("i",[1,2,3,4,5])print(temp_array.index(2))temp_array.insert(2,6)print(temp_array) Output:
(int **) variable and allocateintpointer array of row size in the array. Next, we loop over this pointer array and allocate theintarray of column size each iteration. Lastly, when we finish the 2D array operation, we need to free up the allocated memory. Notice, that deallocation is ...
Here, we have to declare, initialize and access a vector in C++ STL. C++ Vector Declaration Below is the syntax to declare a vector: vector<data_type> vector_name; Since, vector is just like dynamic array, when we insert elements in it, it automatically resize itself. ...
