Question 5
Back to Exercise
What is the output of the following C program?
#include <stdio.h>
int main(void) {
int m[2][3] = {{1}, {4, 5}};
for (int r = 0; r < 2; r++)
for (int c = 0; c < 3; c++)
printf("%d ", m[r][c]);
printf("\n");
return 0;
}- A 1 4 5 0 0 0
- B 1 0 0 4 5 0 Correct
- C 1 1 1 4 5 5
- D Garbage values
Correct Answer: Option B
Each inner brace fills one row, and missing elements of a row become 0: row 0 = 1 0 0, row 1 = 4 5 0. Without the inner braces the values would fill row 0 first.
