How to Calculate of sub element of 2D array and How to print it in c

Calculating Sub-Elements in a 2D Array and Printing Results in C

To calculate the sum of sub-elements of a 2D array in C programming, you can use nested loops to iterate over the rows and columns of the sub-array and add up the elements. Here's an example of how to calculate the sum of a 2x2 sub-array starting from the top-left corner of a 4x4 array:

To calculate the sub-element of a 2D array in C, you can use the following steps:

1. Declare a variable to store the sub-element.
2. Use the following formula to calculate the sub-element:

sub_element = array[row][column];

• array is the 2D array.
• row is the row index of the sub-element.
• column is the column index of the sub-element.

Print the sub-element to the console using the following statement:

printf("%d", sub_element);

For example, the following code shows how to calculate and print the sub-element at row 2, column 3 of a 2D array:

#include <stdio.h>

int main() {
  int array[3][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

  // Calculate the sub-element at row 2, column 3
  int sub_element = array[2][3];

  // Print the sub-element to the console
  printf("%d", sub_element);

  return 0;
}

Output:

9

You can also use a nested loop to iterate over the 2D array and calculate and print the sub-element of each element. For example, the following code shows how to print all the sub-elements of a 2D array:

#include <stdio.h>

int main() {
  int array[3][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

  // Iterate over the 2D array and print the sub-element of each element
  for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
      printf("%d ", array[i][j]);
    }
    printf("\n");
  }

  return 0;
}

Output:

1 2 3
4 5 6
7 8 9
