C Program to specify two dimension array.
/*Program using two dimension array */
#include <stdio.h>
main()
{
/* Local definitions */
int stud[4][2]; /*An array name with 4 rows and 2 columns */
int i;
/* Statements */
for(i=0;i<=3;i++)
{
printf("\n Enter the %d Student roll no and Mark:",i);
scanf("%d %d", &stud[i][0], &stud[i][1]);
} /* for */
for(i=0;i<= 3;i++)
printf("%d Students roll no %d mark %d", i, stud[i][0], stud[i][1]);
} /* main */
OUTPUT
Enter the 0 student roll no and mark: 3977 80
Enter the 1 student roll no and mark: 17776 95
Enter the 2 student roll no and mark: 6682 82
Enter the 3 student roll no and mark: 6683 85
0 student roll no 3977 mark 80
1 student roll no 17776 mark 95
2 student roll no 6682 mark 82
3 student roll no 6683 mark 85
EXPLANATION: Look at the scanf() statement used in the first for loop in the above example. In stud[i][1] and stud [i][1] the first subscript of the variable stud, is row number which changes for every student. The second subscript tells the column number. The following diagram shows how the data is stored in the memory.
Note that all data stored in continuous memory location.
i.e., 3977 is stored in stud [0][0], 80 is stored in stud [0][1] and so on. In fact two dimensional array is nothing but a collection of a number of one dimensional arrays placed one below the other.
