What is the difference between one-dimensional array and two-dimensional array?

The difference between one-dimensional array and two-dimensional array is: each element in one-dimensional array has only one subscript, which is essentially a linear collection of the same type of data, while in two-dimensional array Each element can be used as an array, which is essentially an array with arrays as array elements.

The difference between one-dimensional array and two-dimensional array

Each element in a one-dimensional array With only one subscript, it is essentially a linear collection of the same type of data, and each element in a two-dimensional array can be used as an array. It is essentially an array with an array as an array element.

One-dimensional array:

One-dimensional array can use subscript variables in the program, which means that the entirety of these variables is an array, and each element in the array The data types of the variables are the same.

When each element in the array has only one subscript, such an array is called a one-dimensional array.

One-dimensional array is a single-structured array composed of numbers arranged in a simple sorting structure. One-dimensional arrays are the most basic arrays in computer programs. Two-dimensional and multi-dimensional arrays can be regarded as generated by multiple superpositions of one-dimensional arrays.

Arrays are an important concept in computer programming. Using arrays can easily process large-scale data.

Two-dimensional array:

A two-dimensional array is essentially an array with an array as an array element, that is, an "array of arrays", type specifier array name [constant expression][constant expression].

A two-dimensional array is also called a matrix, and a matrix with equal numbers of rows and rows is called a square matrix. Symmetric matrix a[i][j] = a[j][i], diagonal matrix: There are zero elements outside the main diagonal of an n-order square matrix.
