二维数组的求和c语言

## Summing a 2D Array in C.

Introduction.

A 2D array, also known as a matrix, is a data structure

that stores elements in a two-dimensional grid. Each

element is identified by two indices, one for the row and

one for the column. Summing a 2D array involves adding up

all the elements in the array.

C Code.

The following C code demonstrates how to sum a 2D array:

c.

#include

int main() {。

// Declare and initialize a 2D array.

int array[2][3] = {。

{1, 2, 3},。

{4, 5, 6}。

};

// Calculate the number of rows and columns in the

array.

int rows = sizeof(array) / sizeof(array[0]);

int columns = sizeof(array[0]) / sizeof(int);

// Initialize the sum to 0。

int sum = 0;
