What is printed by the following ANSI C program? #include<stdio.h> int main(int argc, char *argv[]) { int a[3][3][3] = {{1, 2, 3, 4, 5, 6, 7, 8, 9}, {10, 11, 12, 13, 14, 15, 16, 17, 18}, {19, 20, 21, 22, 23, 24, 25, 26, 27}}; int i = 0, j = 0, k = 0; for( i = 0; i < 3; i++){ for(k = 0; k < 3; k++) printf("%d ", a[i][j][k]); printf(" "); } return 0; }

1. 1 2 3 10 11 12 19 20 21
2. 1 4 7 10 13 16 19 22 25
3. 1 2 3 4 5 6 7 8 9
4. 1 2 3 13 14 15 25 26 27

Correct answer: 1 2 3 10 11 12 19 20 21

Solution

The program initializes a 3D array and uses nested loops to print the elements. The outer loop iterates over the first dimension, while the inner loop accesses the second dimension with a fixed index of 'j' (which is always 0), resulting in the first slice of the array being printed for each iteration.
