Operations on 2 Dimensional Array in C language

2D Array in C lang.

#include <stdio.h>

int main()

{

    // 1_D Array

    // variable name contains pointer of first element

    int array_1d[4] = {1, 2, 3, 4};

    printf("Element by value : %d\n", array_1d[2]);

    printf("Element by using pointer : %d\n", *(array_1d + 1));

    // 1_D character array

    char char_arr[4] = {'a', 'b', 'c', 'd'};

    printf("character by value : %c\n", char_arr[2]);

    printf("character by pointer : %c\n\n", *(char_arr + 2));

    int array_2d[3][2] = {{0, 0}, {2, 3}, {1, 5}};

    // i //  0       1       2

    // j // 0  1     0  1    0   1

    for (int i = 0; i < 3; i++)

        for (int j = 0; j < 2; j++)

        {

            printf("%d  ", (array_2d[i][j]));

        }

        printf("\n");

    }
