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语言二维数组转置    c.
    #include <stdio.h>。
    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;
      // Iterate through each row and column.
      for (int i = 0; i < rows; i++) {。
        for (int j = 0; j < columns; j++) {。
          // Add the current element to the sum.
          sum += array[i][j];
        }。
      }。
      // Print the sum.
      printf("The sum of the array is: %d\n", sum);
      return 0;
    }。
    Explanation.
    The code begins by declaring and initializing a 2D array called `array`. The array is initialized with the values 1, 2, 3, 4, 5, and 6.
    Next, the code calculates the number of rows and columns in the array using the `sizeof` operator. The number of rows is equal to the size of the array divided by the size of the first row, and the number of columns is equal to the size of the first row divided by the size of an integer.
    The code then initializes the sum to 0.
    Nested `for` loops are then used to iterate through each row and column in the array. For each element, the value is added to the sum.
