c++ create multidimensional vector

To create a multidimensional vector in C++, you can follow these steps:

1. Include the necessary header file: cpp #include <vector>

2. Declare the vector: cpp std::vector<std::vector<int>> myVector;

In this example, we are creating a vector of vectors that will store integers. You can replace int with any other data type you want to store in your vector.

1. Initialize the vector with a specific size: ```cpp int rows = 3; // Number of rows int cols = 4; // Number of columns

myVector.resize(rows, std::vector(cols)); ```

The resize function is used to set the size of the vector. In this case, we are setting the number of rows to 3 and the number of columns to 4. Each element in the vector will be initialized with the default value of the data type (0 for int).

1. Accessing elements in the vector: cpp myVector[row][col] = value;

You can access individual elements in the vector using the row and column indices. For example, myVector[0][0] refers to the element in the first row and first column.

You can also use nested loops to traverse the entire vector: cpp for (int row = 0; row < rows; ++row) { for (int col = 0; col < cols; ++col) { // Access and modify elements here } }

1. Adding elements to the vector: cpp myVector.push_back(std::vector<int>());

You can add new rows to the vector using the push_back function. Each new row is represented by a vector.

And that's how you can create a multidimensional vector in C++. Let me know if you need further assistance!
