How do you convert a one-dimensional array into two dimensions?

9 Answers

1. Create a 2d array of appropriate size.
2. Use a for loop to loop over your 1d array.
3. Inside that for loop, you’ll need to figure out where each value in the 1d array should go in the 2d array. Try using the mod function against your counter variable to “wrap around” the indices of the 2d array.

What are one-dimensional and two-dimensional arrays?

A one-dimensional array is a list of variables with the same data type, whereas the two-Dimensional array is ‘array of arrays’ having similar data types. A specific element in an array is accessed by a particular index of that array.

What is a 1 dimensional array?

A one-dimensional array (or single dimension array) is a type of linear array. Accessing its elements involves a single subscript which can either represent a row or column index.

What is a one-dimensional array in C?

A one-dimensional array is a structured collection of components (often called array elements) that can be accessed individually by specifying the position of a component with a single index value.

What is a 2 dimensional array?

A two-dimensional array is similar to a one-dimensional array, but it can be visualised as a grid (or table) with rows and columns. Positions in a two dimensional array are referenced like a map using horizontal and vertical reference numbers. They are sometimes called matrices.

What is two-dimensional array with example?

A 2D array has a type such as int[][] or String[][], with two pairs of square brackets. The elements of a 2D array are arranged in rows and columns, and the new operator for 2D arrays specifies both the number of rows and the number of columns. For example, int[][] A; A = new int[3][4];

What is two-dimensional array in C++?

A two-dimensional array in C++ is the simplest form of a multi-dimensional array. It can be visualized as an array of arrays. A two-dimensional array is also called a matrix. It can be of any type like integer, character, float, etc. depending on the initialization.

How do 2 dimensional arrays work?

Two-dimensional (2D) arrays are indexed by two subscripts, one for the row and one for the column. Each element in the 2D array must by the same type, either a primitive type or object type.
