Question

#include <stdio.h>

int a[2][3] = {
{3, 2, 6},
{4, 5, 20}
};
printf("Element 3 in row 2 is %d\n", a[1][2]);

printf("Element 3 in row 2 is %d\n", a[2][2]);

return 0;
}

Answer 1

Arrays start at index 0.

Answer 2

Muhtasinul in two-dimensional arrays it is row first, then column. So [1][2] is the address of the second row, third column. Study carefully Jayakrishna🇮🇳's answer.

Answer 3

int a[2][3];
Colomn indexes
0. 1. 2
Row index:
0: {3 , 2, 6},
1: {4, 5, 20}
Max index is a[1][2]. Next a[2][2] invalid so garbage value..

Answer 4

Check it again, it's 20 am getting...

Answer 5

Thnx😇

Answer 6

But if i input [1] [2]...the result 20 doesn't come...so what can be the problem?

Answer 7

Also...i am confused that [1][2] indicate column first,then row or row first, then column?
