C – Two Dimensional Arrays

Two dimensional arrays:

• Two-dimensional array stores data of format (Rows & Columns).
• Nested loops are used to access locations.

Print default values of 2-dimensional array:

int main() {             int arr[3][3], i, j;             printf(“Array elements are : \n”);             for(i=0 ; i<3 ; i++)             {                         for(j=0 ; j<3 ; j++)                         {                                     printf(“%d \t”, arr[i][j]);                         }                         printf(“\n”);             }             return 0;           }

Two-dimensional array initialization:

int main() {             int arr[3][3] = {10,20,30,40,50,60,70, 80,90};             int i, j;             printf(“Array elements are : \n”);             for(i=0 ; i<3 ; i++)             {                         for(j=0 ; j<3 ; j++)                         {                                     printf(“%d \t”, arr[i][j]);                         }                         printf(“\n”);             }           }
